Description
Populates a string list with the names of key fields in a table.
Call GetKeyFieldNames to retrieve a list of primary key fields from a table.
AConnectionName is the connection name to use.
ACatalogName, ASchemaName, ATableName identifies the table whose primary field names you want to be added to the list.
APattern is the LIKE-pattern for filtering field names.
AList is a TStrings descendant that receives the primary key field names. Any existing strings are deleted from the list before GetKeyFieldName adds the names of the primary key fields in ATableName.
The field names are normalized (enclosed in quotes), if required; otherwise, they are converted to default database dictionary case sensitive/insensitive.
Example
FDManager.GetKeyFieldNames('myconn', 'NORTHWIND', 'DBO', 'MYTAB', '', ListBox1.Items);
