Method Details

setVendor

public void setVendor(EDbVendor dbVendor)

this method is used to set the vendor. this method is used temporarily due to ODBC use the TSqlCmdsMssql

Parameters:

dbVendor -

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

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

getStatementTypeForToken

public ESqlStatementType getStatementTypeForToken(TSourceToken token)

Description copied from interface: ISqlCmds

Finds SQL command type for yacc parser integration. Used by vendor-specific yacc parsers to identify statement types.

Specified by:

getStatementTypeForToken in interface ISqlCmds

Overrides:

getStatementTypeForToken in class AbstractSqlCmds

Parameters:

token - Token to analyze

Returns:

SQL statement type, or sstunknown if not recognized

issql

public TCustomSqlStatement issql(TSourceToken token,
 EFindSqlStateType state,
 TCustomSqlStatement currentStatement)

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:

token - Current token being analyzed

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

currentStatement - Current statement being built (may be modified)

Returns:

The identified or modified SQL statement
