Method Details

createSqlParser

public static TSQLParser createSqlParser(String sql,
 String parsedObjectName,
 List<Object> errors)

Creates a Microsoft SQL parser from string input.

Parameters:

sql - T-SQL string to parse

parsedObjectName - name of the object being parsed (for error reporting)

errors - list to collect parsing errors

Returns:

configured TSQLParser instance

createSqlParser

public static TSQLParser createSqlParser(InputStream is,
 String charset,
 String parsedObjectName,
 List<Object> errors)
                                  throws IOException

Creates a Microsoft SQL parser from input stream.

Parameters:

is - input stream containing T-SQL

charset - character encoding of the stream

parsedObjectName - name of the object being parsed (for error reporting)

errors - list to collect parsing errors

Returns:

configured TSQLParser instance

Throws:

IOException - if there's an error reading the stream

parseSqlStream

public static void parseSqlStream(InputStreamProvider inputStream,
 String parsedObjectName,
 DiffSettings diffSettings,
 int monitoringLevel,
 IMsContextProcessor listener,
 Queue<AntlrTask<?>> antlrTasks)

Parses Microsoft SQL stream asynchronously.

Parameters:

inputStream - provider of the input stream

parsedObjectName - name of the object being parsed

diffSettings - unified context object containing settings, monitor, and error accumulator

monitoringLevel - level of parse tree monitoring

listener - processor for the parsed content

antlrTasks - queue for parser tasks

checkToClean

public static void checkToClean(long cleaningInterval)

Checks if parser caches need cleaning based on last usage time.

Parameters:

cleaningInterval - time interval in milliseconds after which cache should be cleaned

cleanCacheMsParser

public static void cleanCacheMsParser()

Clears the MS SQL parser cache.
