All Implemented Interfaces:

ISqlCmds

public class TSqlCmdsExasol
extends TSqlCmdsMssql

Exasol SQL command resolver.

Exasol shares the MSSQL lexer/parser (see TGSqlParser delegation), so T-SQL statement recognition is inherited from TSqlCmdsMssql. Exasol-specific administrative commands (EXPORT, IMPORT, CREATE CONNECTION, COMMENT ON, ALTER SESSION/SYSTEM, ...) are recognized here by first-token text so they work even though those words are plain identifiers in the MSSQL lexer. Matched statements are routed to TUnknownSqlStatement with a dedicated statement type: split and typed, consumed as a raw token stream without invoking the yacc parser — the same route TSqlCmdsSybase uses for Sybase IQ administrative commands.

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.

Specified by:

issql in interface ISqlCmds

Overrides:

issql in class TSqlCmdsMssql

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
