Avoid unnecessary execution of SQL. This is huge in performance tuning of programs, especially batch programs because they tend to process more data. Another of those "What's the DB2 equivalent to this Sybase syntax" I use local variables in Sybase SQL scripts to hold values for use later in the script. For example: declare @timenow datetime select @timenow = getdate() delete from TableA where activity_date < @timenow delete from TableB where activity_date < @timenow As DB2/SQL and COBOL field declarations are different, It is important to have Equivalanet COBOL data types to the corresponding DB2 table columns in COBOL programs to process the data correctly. More importantly, the precompiler uses the equivalent SQL data types for the declared Host variables. Provide a project name and a location to save your project.

The resulting qualified or rejected rows are independent of the access path that is chosen for that table. DB2 Predicates in SQL statements are classified. COALESCE DB2 function returns the first non-null value in a list of input expressions. This function takes a comma separated list of arguments which are evaluated in the order in which they are specified and returns the first non-NULL value found. Of course, this is just one example of many, many scalar functions supported by DB2. For a complete list of the available functions, refer to Chapter 3 of the IBM DB2 SQL Reference manual.

Fix List for DB2 Version 9.5 for Linux, UNIX and Windows IZ44732, 2, SIGBUS IN COBOL DB2 API SAMPLE PROGRAMS WITH NO EMBEDDED SQL ON SOLARIS POSSTR() IN A DATABASE HAVING COLLATION UCA500R1_LRU_S2.

The locate and posstr functions of DB2 first describe the usage of the two functions: locate (arg1, arg2, ) to find the location where arg1 appears for the first time in arg2, specifying pos, the first position of arg1 appears at the pos of arg2.

Most DB2 predicates are based on the columns of a table. They either qualify rows (through an index) or reject rows (returned by a scan) when the table is accessed. The resulting qualified or rejected rows are independent of the access path that is chosen for that table. DB2 Predicates in SQL statements are classified.
