Db2 z os insert multiple rows in one statement

Multiple-row insert and fetch statements are supported by any requester or server that supports the DRDA Version protocols. It uses a different approach than shown in your question (i.e does not use the VALUES clause as you tried). Inserting multiple rows with DB2Command. If you are inserting many rows in a loop via a single-row insert , you call DBfor every single row , which means you spend some time for the communication with the DB2. On the other han if you use multi-row insert instea you are passing more data within one call and thus reducing the DBcalls.


Optional: Embed the INSERT statement in an application program to insert multiple rows into a table from the values that are provided in host variable arrays. This situation includes the following cases: For static or dynamic MERGE statements , of the FOR n ROWS clause contains a constant value for n. Use host variable arrays in the VALUES clause of the INSERT FOR n ROWS statement to insert multiple rows into a table. You can add new data to an existing table in other ways, too. DBManuals says we can insert multiple rows in a single insert statement.


As a matter of fact this syntax works only on DBLUW (Linux, Unix, Windows). It is not supported in DBV 7. You can use a select-statement within an INSERT statement to insert zero , one , or more rows into a table from the result table of the select-statement. One use for this kind of INSERT statement is to move data into a table you created for summary data. The dbmanual only says that there is a provision for the insertion of multiple rows using single insert statement (the code which i pasted is a ex.). It seems a multi row insert using static values can be done only from a program using a host array of values.


A multi row insert using static values cannot be done using Spufi or any other dynamic sql tool. To do this I have to code a full select statement after the INSERT statement. The SQL reference manual is not clear about this. If am right it is not supported in Vtoo.


As a result, PowerExchange accesses the database fewer times, which improves bulk data movement performance. You could insert one row at a time using the INSERT with a VALUE clause or insert multiple rows via an INSERT that included a SELECT clause from another table. Until now we have had no way to insert multiple new rows with a single statement although there have been.


EXEC SQL INSERT INTO test-table (col col col3) VALUES (:HV-ACT-NMBR-ARRAY, :HV-ACT-CITY-ARRAY, :HV-ACT-NAME-ARRAY) FOR ROWS ATOMIC END-EXEC. In this example, the INSERT into table column is the same as any other INSERT statement you might. My first detailed entry will introduce you to multi- row INSERT and FETCH. When you use multiple - row FETCH and INSERT statements , DBfetches or inserts multiple rows of data at one time.


This Version SQL enhancement does exactly what you would expect. It allows you for the first time, to insert multiple rows or fetch multiple rows with a single SQL statement. Include multiple row contents in the VALUES clause. For example, this will insert three rows: INSERT INTO mytable VALUES ( ‘abc’), ( ‘def’), ( ‘ghi’) Use array insert in CLI. DBuses the LOAD utility to bulk load multiple rows into a table and it will be more efficient than a series of INSERT statements.


With only one SQL statement , DBcan insert or update multiple rows in the table and return the values back to the application. This capability reduces application complexity and helps eliminate potentially millions of SQL calls in nightly batch processing cycles improving DBSQL performance dramatically. In db, how do you insert multiple rows in query using a. DB: Hello people I need to enter more then one value in table but by using following command I can only enter one record viz.
