Functions

func FetchDDLTableNames

func FetchDDLTableNames(schema string, stmt ast.StmtNode) ([]*filter.Table, error)

FetchDDLTableNames returns table names in ddl the result contains [tableName] excepted create table like and rename table for `create table like` DDL, result contains [sourceTableName, sourceRefTableName] for rename table ddl, result contains [oldTableName, newTableName]

func Parse

func Parse(p *parser.Parser, sql, charset, collation string) (stmt []ast.StmtNode, err error)

Parse wraps parser.Parse(), makes `parser` suitable for dm

func RenameDDLTable

func RenameDDLTable(stmt ast.StmtNode, targetTableNames []*filter.Table) (string, error)

RenameDDLTable renames table names in ddl by given `targetTableNames` argument `targetTableNames` is same with return value of FetchDDLTableNames

func SplitDDL

func SplitDDL(stmt ast.StmtNode, schema string) (sqls []string, err error)

SplitDDL splits multiple operations in one DDL statement into multiple DDL statements if fail to restore, it would not restore the value of `stmt` (it changes it's values if `stmt` is one of DropTableStmt, RenameTableStmt, AlterTableStmt)
