I am facing one Issue while fetching a column from a DB2 table. Running a SQL in the JCL using DB2 UNLOAD utility to extract result into a dataset. 1) When I use below CASE statement in SELECT clause. ST_CD is the last column in the select clause after delimiter '#]&#' Data base declaraion is CHAR(2) CASE WHEN ST_CD IS NULL THEN ' '

Introduction to Db2 LOCATE () function The LOCATE () function returns the position at which the first occurrence of a substring starts within another string. The following illustrates the syntax of the LOCATE () function: LOCATE (search_string,source_string, start,string_unit)

It is recommended that if either the search-string or source-string contains mixed data, POSITION should be used instead of POSSTR. The POSITION function operates on a character basis. The SUBSTR function accepts mixed data strings. However, because SUBSTR operates on a strict byte-count basis, the result will not necessarily be a properly formed mixed data string. start An expression that specifies the position within string-expression to be the first character of the result. Often, in our applications, we need to work with text strings, and DB2 SQL can come in very useful and simplify our code. In this guide we see some interesting SQL functions for string manipulation: POSSTR – Search for position within a string; LOCATE and LOCATE_IN_STRING – Find the location with a few more options 2014-09-04 · POSSTR – DB2 Function.

This could be done from an anonymous block or stored procedure. You put this in a function (UDF): POSSTR – DB2 Function Similar to the LOCATE function, but with the arguments reversed.POSSTR returns the position of the first occurrence of the second argument within the first argument. 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.

Hope you learned something by reading this short blog post. Leave comments on what other SQL you use to get some common metrics against your DB2 database ?

DB2 Administrative SQL Cookbook: List Privileged IDs that do not Have the Connect Authority Purpose To list IDs that have one or more privileges, but do not have the CONNECT authority through a direct grant, a group, or a role, either explicitly or implicitly.

but i have seen db2 using indexes even when using column function. what is the criteria of db2 about picking index or not picking index when there is a column function ? i am using function on one column like below SUBSTR(abc,1,1) IN ('SS',V'V',OO',PP',EE') and db2 is doing table scan and Filter Factor : 0.0798775 DB2 Administrative SQL Cookbook: List Privileged IDs that do not Have the Connect Authority Purpose To list IDs that have one or more privileges, but do not have the CONNECT authority through a direct grant, a group, or a role, either explicitly or implicitly. 2010-09-17 · Function use is common in IBM DB2 SQL. However, use and misuse of functions can affect query access paths and performance.

The result will be “ANA”. Apart from Trim functions, you can use RIGHT and LEFT functions to handle strings and to get substring.. Rules for LEFT and RIGHT Functions.

Zero is returned if no match is found. Replace all occurrence of a substring in a string with a new substring. RIGHT: Extract a substring that consists of the number of rightmost characters from a string.
