Method Details

initializeCommands

protected void initializeCommands()

Description copied from class: AbstractSqlCmds

Initialize vendor-specific commands. Subclasses must implement this to populate sqlCmdList.

Specified by:

initializeCommands in class AbstractSqlCmds

getToken1Str

protected String getToken1Str(int token1)

Description copied from class: AbstractSqlCmds

Get the string representation for vendor-specific token codes. Subclasses should override this method to provide mappings for vendor-specific reserved words (tokens > TBaseType.rrw_abort).

Overrides:

getToken1Str in class AbstractSqlCmds

Parameters:

token1 - Token code

Returns:

String representation of the token, or null if not applicable

issql

public TCustomSqlStatement issql(TSourceToken pcst,
 EFindSqlStateType pstate,
 TCustomSqlStatement psqlstatement)

Description copied from interface: ISqlCmds

Identifies the SQL statement type from a token stream. This method is called repeatedly during parsing to identify statement boundaries and types in complex SQL scripts.

Parameters:

pcst - Current token being analyzed

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
