ADD-LIKE-FIELD( ) method

Adds a field, like the specified source field, to the temp-table.

This method cannot be called after TEMP-TABLE-PREPARE( ) has been called unless CLEAR( ) is called first.

Return type: LOGICAL

Applies to: Temp-table object handle

Syntax

ADD-LIKE-FIELD( field-name-exp , source-buffer-field-handle-exp | source-db-field-name-exp )

field-name-exp

A character expression that evaluates to the name of the field to be created in the temp-table.

source-buffer-field-handle-exp

A character expression that evaluates to a buffer-field handle from which to copy the field.

source-db-field-name-exp

A character expression that evaluates to a database field name from which to copy the field. The table name must be qualified with the database name.

The following example fragments add a field to a temp-table, the first from a named source and the second from a buffer-field handle source:

tth:ADD-LIKE-FIELD("ordno","Order.OrderNum").

tth:ADD-LIKE-FIELD(bfh:NAME, bfh).

Note: There is a limit to the number of fields that can be accommodated in a temp-table object. The limit depends on how large the field information (initial value, validate information, help messages, etc.) is, but you should plan on a limit of approximately 1,000 fields.
