public interface ISqlCmds

Interface for vendor-specific SQL command resolution. Provides methods for identifying SQL statement types and resolving commands used by both the main parser and vendor-specific yacc parsers.

Since:

3.1.0.9

Method Summary

Modifier and Type	Method and Description
TSqlCmdList	getSqlCmdList() Gets the command list for this vendor (for compatibility and debugging).
ESqlStatementType	getStatementTypeForToken(TSourceToken token) Finds SQL command type for yacc parser integration.
EDbVendor	getVendor() Gets the vendor this command resolver handles.
TCustomSqlStatement	issql(TSourceToken token, EFindSqlStateType state, TCustomSqlStatement currentStatement) Identifies the SQL statement type from a token stream.

Method Detail

issql

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

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

getStatementTypeForToken

ESqlStatementType getStatementTypeForToken(TSourceToken token)

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

Parameters:

token - Token to analyze

Returns:

SQL statement type, or sstunknown if not recognized

getVendor

EDbVendor getVendor()

Gets the vendor this command resolver handles.

Returns:

Database vendor

getSqlCmdList

TSqlCmdList getSqlCmdList()

Gets the command list for this vendor (for compatibility and debugging).

Returns:

Command list containing all recognized commands
