SELECT SUBSTR(NAME, 5, 15) AS NAME_SUBSTR FROM CATENTDESC; The above query will take and substring the NAME column in the CATENTDESC table starting with the 5th character, and returning a resulting substring that is 15 characters in length. NOTE: There are a few important considerations to make regarding the DB2 SUBSTR function:

Examples of scalar functions that are addressed in this course: SUBSTR; POSSTR; COALESCE/VALUE; DECIMAL; ROUND; DIGITS; CHAR; DATE/TIME. Table

In MySQL and Oracle, length is an optional argument. When length is not specified, the entire string starting from the position-th character is returned.In SQL Server, length is required. SUBSTR() can be used in SELECT, WHERE, and Listserv Db2 forum poster proposal: how to handle negative DBIDs (DataBase object Identifier) using the faster and easier ASCII Built-In Scalar function instead of LOCATE and HEX.

This course is appropriate for customers working in all DB2 environments, specifically for z/OS, Linux, UNIX, and Windows. POSSTR to INSTR.

Since INSTR () isn't available, it can't be used with DB2 on i. However, POSSTR () can be used and it can locate the position of a search-string within a string. The LENGTH () function can give the length of the search string. Those two values together essentially tell where the colon will be. The POSSTR function returns the starting position of the first occurrence of one string (called the search-string) within another string (called the source-string). Numbers for the search-string position start at 1 (not 0). The result of the function is a large integer.

Not all SQL situations are rewritable but with the XMLPARSE and the SUBSTR and POSSTR clauses, the SQL is easily rewritten and resolved for using the IDAA Accelerator appliance. IDAA can have a huge impact on your overall processing. In this tutorial we'll see how we can chop off strings and use only parts of them using the SUBSTR(), RIGHT() and LEFT() Functions. Because of the fancy functions, CTEs, and Recursive SQL, V8 was possibly my favourite release of DB2, when SQL could do absolutely anything, so I did not need REXX post processors any more. I forgot to mention Native SQL Stored Procs, and Non-Padded VARCHAR in indexes, DPSIs.
