Method Detail

getToken1Str

protected String getToken1Str(int token1)

Description copied from class: AbstractSqlCmds

Parameters:

token1 - Token code

Returns:

String representation of the token, or null if not applicable

pstate - Current parsing state (start, in body, or in exception)

psqlstatement - Current statement being built (may be modified)

Returns:

The identified or modified SQL statement
