charsetNameForDatabase

public ConcurrentMap<String,String> charsetNameForDatabase()

Provides a map of default character sets by database/schema name.

Returns:

map of default character sets.

parseName

public String parseName(MySqlParser.UidContext uidContext)

Parse a name from MySqlParser.UidContext.

Parameters:

uidContext - uid context

Returns:

name without quotes.

parseQualifiedTableId

public TableId parseQualifiedTableId(MySqlParser.FullIdContext fullIdContext)

Parse qualified table identification from MySqlParser.FullIdContext. AbstractDdlParser.currentSchema() will be used if definition of schema name is not part of the context.

Parameters:

fullIdContext - full id context.

Returns:

qualified TableId.

parsePrimaryIndexColumnNames

public void parsePrimaryIndexColumnNames(MySqlParser.IndexColumnNamesContext indexColumnNamesContext,
                                         TableEditor tableEditor)

Parse column names for primary index from MySqlParser.IndexColumnNamesContext. This method will updates column to be not optional and set primary key column names to table.

Parameters:

indexColumnNamesContext - primary key index column names context.

tableEditor - editor for table where primary key index is parsed.

currentDatabaseCharset

public String currentDatabaseCharset()

Get the name of the character set for the current database, via the "character_set_database" system property.

Returns:

the name of the character set for the current database, or null if not known ...

runIfNotNull

public void runIfNotNull(Runnable function,
                         Object... nullableObjects)

Runs a function if all given object are not null.

Parameters:

function - function to run; may not be null

nullableObjects - object to be tested, if they are null.

parseSetAndEnumOptions

public static List<String> parseSetAndEnumOptions(String typeExpression)

Parse the ENUM or SET data type expression to extract the character options, where the index(es) appearing in the ENUM or SET values can be used to identify the acceptable characters.

Parameters:

typeExpression - the data type expression

Returns:

the string containing the character options allowed by the ENUM or SET; never null

getConverters

public MySqlValueConverters getConverters()

getTableFilter

public Tables.TableFilter getTableFilter()
