Popis školení:

This course provides an introduction to the SQL language and applies to the entire DB2 Family, and Informix. This course is appropriate for customers working in all DB2 environments, that is, z/OS, VM/VSE, iSeries, Linux, UNIX, and Windows. It is also appropriate for customers working in an Informix environment.

Osnova školení:

  • Describe factors relevant to the BIND process, including RUNSTATS positioning, package status, parameters, and authorization requirements

  • Program structure II

  • Use DECLARE, OPEN, FETCH, and CLOSE CURSOR statements to handle select criteria that may return multiple rows in application programs
