The SELECT INTO statement produces a result table that contains at most one row. The statement assigns the values in that row to host variables. If the table is empty, the statement does not assign values to the host variables. DB2 10 - DB2 SQL - SELECT INTO

The SQL SELECT INTO Statement. The SELECT INTO statement copies data from one table into a new table. SELECT INTO Syntax. Copy all columns into a new table: In DB2 if you need to populate a table, you need to use INSERT INTO, like in this example: INSERT INTO new_tableSELECT col1,col2 FROM source_tableWHERE col1='something'; and if you need to populate query variable, you need to use SELECT INTO, like in this example: Select into is for SQL Server (or orther in dont know). For DB2 instruction for save query into table is : create table newtable as ( SELECT * FROM oldtable ) with data Important not eon SELECT INTO and VALUES INTO: These statements are allowed in SQL Procedures (SQL PL) but not in Triggers and SQL Functions (inline SQL PL). For the later use the (multicolumn) SET statement.

At the top of the page is a link to "IBM Manuals". Among these are documentation for multiple releases of DB2. Select the SQL Reference for your release and search for WHERE EXISTS (the flashlight/tubelight near the top left). In the same manual is lots of discussion about SELECT (probably much more than you want - but it is there)

The picture clause that should be used for the DB2 null indicator is S9(4) COMP. Meaning: Se hela listan på tutorialspoint.com it's missing the FROM clause. Hence the need in DB2 to refer to the dummy table. Populating the variable is a different story, as that's in a procedural context and the current date is coming from a special register.

does not use bufferpools, so every select, insert, update, or delete of a. LONG VARCHAR requires direct disk I/O, just like LOBs. In order to use 

In this section, we want to join multiple tables together. DB2 allows you to use a SELECT statement returning a scalar value, for example SELECT COUNT(*), in the IF statement. The result of the query can be used in a boolean expression. For the complete syntax, see SELECT. Another way to set a variable's value is the SET statement. SELECT INTO results are not stored in the query cache even if SQL_CACHE is specified.

SELECT INTO OUTFILE writes the resulting rows to a file, and allows the use of column and row terminators to specify a particular output format.

DB2 10 - DB2 SQL - SELECT INTO The SELECT statement can be any valid query that returns zero or more rows. The number of columns and their data type must match with the column list in the INSERT INTO clause. We often use the INSERT INTO SELECT statement to copy data from a table to another table; or to insert summary data of a table into another table. Db2 INSERT INTO SELECT examples WITH tables ( name ) AS (SELECT tab.name FROM sysibm.SYSTABLES tab FETCH FIRST 5 rows only ) , views ( name ) AS (SELECT vie.name FROM sysibm.SYSVIEWS vie FETCH FIRST 5 rows only ) SELECT name FROM tables UNION SELECT name FROM views; Share.

INSERT INTO SELECT Syntax. Copy all columns from one table to another table: DB2 Application Programming and SQL Guide; DB2 SQL Reference; Summary. Without proper knowledge of dynamic SQL you are going into battle without a full set of ammunition. Seriously consider using dynamic SQL under the following conditions: When the nature of the application program is truly changeable, not just a series of static SQL statements A DB2 null Indicator/value is not the same as Zero or blank. For all Columns that can contain Nulls, indicator variable should be used in all Select Statements to retrieve data -or- the COALESCE built-in function should be used. Syntax: INTO :HOSTVAR:NULLIND. The picture clause that should be used for the DB2 null indicator is S9(4) COMP.
