Часто задаваемые вопросы
What is a host variable?
A host variable is a field in your program that is specified in an SQL statement, usually as the source or target for the value of a column.
What is an indicator variable?
An indicator variable is a halfword integer variable used to communicate additional information about its associated host variable.
How do I handle SQL error return codes?
When an SQL statement is processed in your program, SQL places a return code in the SQLCODE and SQLSTATE fields.
How do I use the SQL diagnostics area?
The SQL diagnostics area is used to keep the returned information for an SQL statement that has been run in a program.
