liqubase on update 语法

liqubase on update 语法

LiQuibase是一个用于数据库变更管理的开源工具,它能够跟踪、管理和应用数据库的变更,保证数据库变更的可追溯性和可重复性。

在LiQuibase中,update语法是非常重要的一部分,它用于对数据库进行更新操作,包括新增表、修改表结构、插入数据等。

LiQuibase中的update语法具有一定的特点和使用规则,下面就来详细介绍一下:一、update语法的基本结构update语法的基本结构包括标签、属性和内容三部分,其中标签用于标识该变更的类型,属性用于指定变更的具体信息,内容用于描述变更的具体操作。

二、update语法的常用标签1. createTable:用于创建表。

2. addColumn:用于向表中添加列。

3. dropColumn:用于删除表中的列。

4. renameColumn:用于重命名表中的列。

5. modifyColumn:用于修改表中列的属性。

6. insert:用于向表中插入数据。

7. update:用于更新表中的数据。

8. delete:用于删除表中的数据。

三、update语法的属性设置在使用update语法时,需要根据具体的变更类型设置相应的属性,例如创建表时需要设置表名、列名、数据类型、约束条件等属性。

四、update语法的使用示例下面通过一个简单的示例来演示update语法的使用:```xml<changeSet author="John" id="1"><createTable tableName="user"><column name="id" type="INT"><constr本人nts nullable="false" primaryKey="true"/></column><column name="name" type="VARCHAR(50)"><constr本人nts nullable="false"/></column><column name="age" type="INT"/></createTable></changeSet>```在这个示例中,我们使用了createTable标签来创建了一个名为user 的表,该表包括id、name和age三个列,其中id列为INT类型且设置了主键约束,name列为VARCHAR(50)类型且设置了非空约束,age列为INT类型且没有设置约束。

ABAP语法讲解二(s e l e c t语句)

SELECTBasic formSELECT select clause [INTO clause] FROM from clause [WHERE cond1] [GROUP BY fields1] [HAVING cond2] [ORDER BY fields2].EffectReads a selection and/or a summary of data from one or more database tables and/or views (see relational database). SELECT is an OPEN SQL statement.Each SELECT statement consists of a series of clauses, each with a differen task:The SELECT clause select clause describes∙Whether the result of the selection should be a single record or a table,∙Which columns should be contained in the result,∙Whether identical lines may occur in the result.The INTO clause INTO clause determines the target area into which the selected data is read. If the target area is an internal table, the INTO clause specifies:∙Whether you want to overwrite the contents of the internal table or∙Append the results to the internal table, and∙Whether you want to place the data in the internal table in a single step, or in a series of packages.The INTO clause can also occur after the FROM clause. You may omit it if∙The SELECT clause contains a "*",∙The FROM clause does not contain a JOIN, and∙You have declared a table work area dbtab in your program using TABLES.The data, if it exists in the database, is then made available using the table work area dbtab. The statement is then processed further like the SELECT * INTO dbtab FROM dbtab statement, which has the same effect.If the result of the selection is a table, the data is normally read line by line (for further information, see INTO clause) in a processing loop, which is introduced with SELECT and concludes with ENDSELECT. The loop is processed once for each line that is read. If you want the result of the selection to be a single record, there is no concluding ENDSELECT statement.The FROM clause FROM clause specifies the source of the data (database tables or views), from which you want to select the data. It also specifies the∙Client handling,∙Behavior for buffered tables, and∙The maximum number of lines that you want to read.The WHERE clause cond1 specifies the conditions that the result of the selection must satisfy. By default, only data from the current client is selected (without you having to specify the client field specifically in the WHERE clause). If you want to select data from several clients, you must use the ... CLIENT SPECIFIED addition in the FROM clause.The GROUP BY clause fields1 combines groups of lines into single lines of the result table.A group is a set of records with the same value of each database field listed in the GROUP BY clause.The HAVING clause cond2 specifies conditions for the combined lines of the result table.The ORDER BY clause fields2 specifies how the records in the result table should be arranged.The system field SY-DBCNT contains the number of lines read so far ecah time the SELECT statement is executed. After ENDSELECT, SY-DBCNT contains the total number of records read.The return code is set as follows:SY-SUBRC = 0:The result table contains at least one record.SY-SUBRC = 4:The result table is empty.SY-SUBRC = 8:Applies only to SELECT SINGLE FOR UPDATE: You did not specify all of the primary key fields in the WHERE condition. The result table is empty.NoteThe SELECT COUNT( * ) FROM ... statement returns a result table containing a single line with the result 0 if there are no records in the database table that meet the selection criteria. In an exception to the above rule, SY-SUBRC is set to 4 in this case, and SY-DBCNTto zero.ExampleDisplaying the passenger list for Lufthansa flight 0400 on 2/28/1995:DATA: WA_SBOOK TYPE SBOOK.SELECT * FROM SBOOK INTO WA_SBOOKWHERECARRID = 'LH ' ANDCONNID = '0400' ANDFLDATE = '19950228'ORDER BY PRIMARY KEY.WRITE: / WA_SBOOK-BOOKID, WA_SBOOK-CUSTOMID,WA_SBOOK-CUSTTYPE, WA_SBOOK-SMOKER,WA_SBOOK-LUGGWEIGHT, WA_SBOOK-WUNIT,WA_SBOOK-INVOICE.ENDSELECT.NotePerformance:Storing database tables in a local buffer (see SAP buffering) can lead to considerable time savings in a client/server environment, since the access time across the network is considerably higher than that required to access a locally-buffered table.Notes1. A SELECT statement on a table for which SAP buffering has been declared in theABAP Dictionary usually reads data from the SAP buffer without accessing thedatabase. This does not apply when you use:- SELECT SINGLE FOR UPDATE or- SELECT DISTINCT in the SELECT clause,- BYPASSING BUFFER in the FROM clause,- ORDER BY f1 ... fn in the ORDER BY clause,- Aggregate functions in the SELECT clause,- When you use IS [NOT] NULL in the WHERE condition,or when the table has generic buffering and the appropriate section of the key is not specified in the WHERE condition.2. The SELECT statement does not perform its own authorization checks. You shouldwrite your own at program level.3. Proper synchronization of simultaneous access by several users to the same set ofdata cannot be assured by the database lock mechanism. In many cases, you will need to use the SAP locking mechanism.4. Changes to data in the database are not made permanent until a database commit(see LUW) occurs. Up to this point, you can undo any changes using a databserollback (see Programming Transactions). At the lowest isolation level (see lock mechanism ), the "Uncommitted Read", it can sometimes be the case that dataselected by a SELECT statement was never written to the database. While a program is selecting data, a second program could be adding data to, changing data in, or deleting data from the database at the same time. If the second program thenexecutes a rollback, the first program has selected a set of data that may onlyrepresent a temporary state from the database. If this kind of "phantom data" isunacceptable in the context of your application, you must either use the SAP locking mechanism or change the isolation level of the database system to at least"Committed Read" (see locking mechanism).5. In a SELECT - ENDSELECT loop, the CONTINUE statement terminates the currentloop pass and starts the next.6. If a SELECT - ENDSELECT loop contains a statement that triggers a databasecommit, the cursor belonging to the loop is lost and a program termination andruntime error occur. Remote Function Calls and changes of screen always lead to adatabase commit. The following statements are consequently not allowed wihtin aSELECT-ENDSELECT loop: CALL FUNCTION ... STARTING NEW TASK, CALLFUNCTION ... DESTINATION, CALL FUNCTION ... IN BACKGROUND TASK,CALL SCREEN, CALL DIALOG, CALL TRANSACTION, and MESSAGE.7. On some database systems (for example DB2/390)locking conflicts can be caused even by read access. You can prevent this problemfrom occurring using regular database commits.SELECT ClauseVariants:1. SELECT [SINGLE [FOR UPDATE] | DISTINCT] *2. SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn3. SELECT [SINGLE [FOR UPDATE] | DISTINCT] (itab)EffectThe result of a SELECT statement is itself a table. The SELECT clause, along with the database tables and/or views in the FROM clause, specifies the sequence, name, database type, and length of the columns of the result table.You can also use the optional additions SINGLE or DISTINCT to indicate that only certain lines in the result set should be visible to the program:SINGLEThe result of the selection should be a single entry. If it is not possible to identify a unique entry, the system uses the first line of the selection. If you use the FOR UPDATE addition, the selected entry is protected against parallel updates from other transactions until the next database commit (see LUW and database lock mechanism). If the database system identifies a deadlock, a runtime error occurs. DISTINCTDuplicate entries in the result set are automatically deleted.NoteTo ensure that an entry can be uniquely identified, you can specify all of the fields in the primary key using AND expressions in the WHERE condition.NotePerformance:1. The additions SINGLE FOR UPDATE and DISTINCT bypass the SAP buffering.2. The addition DISTINCT forces a sort on the database server. You should thereforeonly use it if you are really expecting duplicates in the result set.Variant 1SELECT [SINGLE [FOR UPDATE] | DISTINCT] *EffectThe columns of the result set will have exactly the same sequence, names, database type, and length as the fields of the database table or view specified in the FROM clause.ExamplesExample to display all flights from Frankfurt to New York:DATA WA_SPFLI TYPE SPFLI.SELECT * FROM SPFLI INTO WA_SPFLIWHERECITYFROM = 'FRANKFURT' ANDCITYTO = 'NEW YORK'.WRITE: / WA_SPFLI-CARRID, WA_SPFLI-CONNID.ENDSELECT.Example to display the free seats on Lufthansa flight 0400 on 02.28.1995:DATA WA_SFLIGHT TYPE SFLIGHT.DATA SEATSFREE TYPE I.SELECT SINGLE *FROM SFLIGHT INTO WA_SFLIGHTWHERECARRID = 'LH ' ANDCONNID = '0400' ANDFLDATE = '19950228'.SEATSFREE = WA_SFLIGHT-SEATSMAX - WA_SFLIGHT-SEATSOCC.WRITE: / WA_SFLIGHT-CARRID, WA_SFLIGHT-CONNID,WA_SFLIGHT-FLDATE, SEATSFREE.NoteIf you specify more than one table in the FROM clause and the INTO clause contains an internal table or work area instead of a field list, the fields are placed into the target area from left to right in the order in which they occur in the tables in the FROM clause. Gaps may occur between the table work areas for the sake of alignment. For this reason, you should define the target work area by referring to the types of database tables instead of simply listing the fields. For an example, refer to the documentation of the FROM clause.Variant 2SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... snEffectThe columns of the result table will have the same format as the column references s1 ... sn.If si stands for a field f, MAX( f ), MIN( f ), or SUM( f ), the corresponding column in the result set will have the same ABAP Dictionary format as f. For COUNT( f ) orCOUNT( * ) the column has the type INT4. For AVG( f ) it has the type FLTP.If you use aggregate functions with one or more database fields in the SELECT clause, you must include all of the database fields that are not used in the aggregate function in the GROUP BY clause. The result of the selection in this case is a table.If the SELECT clause only contains aggregate functions, the result of the selection will be a single entry. In this case, SELECT does not have a corresponding ENDSELECT statement.Notes1. You can only use this variant for pool and cluster tables if the SELECT clause doesnot contain any aggregate functions.2. As a rule, aggregate functions used together with the FOR ALL ENTRIES addition donot return the desired values. The result is only correct if the fields in the WHEREcondition that are linked with AND and tested for equality with the aggregated fieldscan identify the table line uniquely.3. If you use a database field with type LCHAR or LRAW in the SELECT clause, you mustspecify the corresponding length field immediately before it in the SELECT clause. NotesPerformance:1. When you use aggregate functions, the system bypasses the SAP buffer.2. Since not all database systems can store the number of lines in a table in theircatalog, and therefore retrieving them is time-consuming, the COUNT( * ) functionis not suitable for testing whether a table contains any entries at all. Instead, youshould use SELECT SINGLE f ... for any table field f.3. If you only want to select certain columns of a database table, use a field list in theSELECT clause or a view.ExamplesExample to display all destinations served by Lufthansa from Frankfurt:TABLES SPFLI.DATA TARGET LIKE SPFLI-CITYTO.SELECT DISTINCT CITYTOINTO TARGET FROM SPFLIWHERECARRID = 'LH ' ANDCITYFROM = 'FRANKFURT'.WRITE: / TARGET.ENDSELECT.Example to display the number of airlines that fly to New York:TABLES SPFLI.DATA COUNT TYPE I.SELECT COUNT( DISTINCT CARRID )INTO COUNTFROM SPFLIWHERECITYTO = 'NEW YORK'.WRITE: / COUNT.Example to find the number of passengers, the total luggage weight, and the average weight of the luggage for all Lufthansa flights on 02.28.1995:TABLES SBOOK.DATA: COUNT TYPE I, SUM TYPE P DECIMALS 2, AVG TYPE F.DATA: CONNID LIKE SBOOK-CONNID.SELECT CONNID COUNT( * ) SUM( LUGGWEIGHT ) AVG( LUGGWEIGHT ) INTO (CONNID, COUNT, SUM, AVG)FROM SBOOKWHERECARRID = 'LH ' ANDFLDATE = '19950228'GROUP BY CONNID.WRITE: / CONNID, COUNT, SUM, AVG.ENDSELECT.Variant 3SELECT [SINGLE [FOR UPDATE] | DISTINCT] (itab)EffectWorks like SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn, if the internal table itab contains the list s1 ... sn as ABAP source code, and works like SELECT [SINGLE [FOR UPDATE] | DISTINCT] *, if itab is empty. The internal table itab may only contain one field, which must have type C and not be longer than 72 characters. Youmust specify itab in parentheses. Do not include spaces between the parentheses and the table name.NoteThe same restrictions apply to this variant as to SELECT [SINGLE [FOR UPDATE] | DISTINCT] s1 ... sn.ExampleExample to display all Lufthansa routes:DATA WA_SPFLI TYPE SPFLI,WA_FTAB(72) TYPE C, FTAB LIKE TABLE OF WA_FTAB.CLEAR FTAB. FTAB = 'CITYFROM'. APPEND WA_FTAB TO FTAB. FTAB = 'CITYTO'. APPEND WA_FTAB TO FTAB. SELECT DISTINCT (FTAB) INTO CORRESPONDING FIELDS OF WA_SPFLIFROM SPFLIWHERECARRID = 'LH'. WRITE: / WA_SPFLI-CITYFROM, WA_SPFLI-CITYTO. ENDSELECT.。

sap update 语法
SAP Update 语法是在SAP系统中使用的一种数据操作语言,它可以实现对数据库表中数据的修改、删除和插入等操作。

本文将从以下几个方面详细介绍SAP Update 语法。

一、Update 语句的基本格式
Update 语句的基本格式如下:
UPDATE table_name SET column1 = value1, column2 =
value2, ...WHERE condition
其中,table_name 表示要进行操作的数据库表名;column1、column2 等表示要修改的列名;value1、value2 等表示要修改成的值;condition 表示更新记录时所需满足的条件。

二、Update 语句中 SET 子句
SET 子句用于指定要修改哪些列及其对应的值,它可以包含一个或多个列值对。

列值对之间用逗号分隔,每个列值对由列名和赋给该列的值组成,中间用等号连接。

例如:
UPDATE employees SET salary = 6000, age = 28 WHERE emp_id = '001'
这个例子中,SET 子句指定了要修改 employees 表中 salary 和 age 列,并将其分别赋值为 6000 和 28。

三、Update 语句中 WHERE 子句
WHERE 子句用于指定更新记录时所需满足的条件。

如果 WHERE 子
句被省略,则会更新表中所有记录。

WHERE 子句可以使用比较运算符、逻辑运算符和通配符等来构造条件表达式。

例如:
UPDATE employees SET salary = 6000 WHERE age > 30
这个例子中,WHERE 子句指定了更新 employees 表中 age 大于 30 的记录,并将它们的 salary 列值修改为 6000。

四、Update 语句的使用注意事项
1. Update 语句会直接修改数据库表中的数据,请慎重使用,以免造
成不可逆的后果。

2. 在使用 Update 语句时,一定要加上 WHERE 子句,否则会更新表中所有记录。

3. 在使用 Update 语句时,要确保列名和表名正确无误。

4. 在使用 Update 语句时,要确保更新的数据类型与列定义的数据类型相同。

5. 在使用 Update 语句时,要注意避免死锁问题。

如果多个用户同时对同一个数据进行更新操作,则可能会出现死锁现象。

为避免死锁问题,可以通过调整事务隔离级别等方式来解决。

五、Update 语句的实际应用场景
1. 数据库维护:当需要对数据库中的某些数据进行修改或删除时,可以使用 Update 语句来实现。

例如,在 HR 系统中需要将某些员工的薪资进行调整时,可以使用 Update 语句来实现。

2. 数据库备份:在备份数据库时,可以使用 Update 语句将数据库中的数据更新到备份文件中,以保证备份文件的完整性和准确性。

3. 数据库迁移:当需要将数据从一个数据库迁移到另一个数据库时,可以使用 Update 语句来实现。

例如,在将 HR 系统从 Oracle 数据库
迁移到 SAP HANA 数据库时,可以使用 Update 语句将数据从Oracle 数据库中导出,并更新到 SAP HANA 数据库中。

六、总结
SAP Update 语法是一种强大的数据操作语言,它可以实现对数据库表中数据的修改、删除和插入等操作。

在使用 Update 语句时,要注意遵循基本格式,并加上 WHERE 子句以避免更新所有记录。

Update 语句在数据库维护、备份和迁移等方面都有广泛应用。
