Functions

func CloseContextRootFinalizer added in v0.8.0 

func CloseContextRootFinalizer(ctx *sql.Context) error

CloseContextRootFinalizer finalizes any changes persisted within the context by writing them to the working root. This should ONLY be called by the ContextRootFinalizer node.

func GetCollectionFromContext added in v0.8.0 

func GetCollectionFromContext(ctx *sql.Context) (*sequences.Collection, error)

GetCollectionFromContext returns the given sequence collection from the context. Will always return a collection if no error is returned.

func GetCurrentSchema added in v0.7.5 

func GetCurrentSchema(ctx *sql.Context) (string, error)

GetCurrentSchema returns the current schema used by the context. Defaults to "public" if the context does not specify a schema.

func GetDoltTableFromContext added in v0.12.0 

func GetDoltTableFromContext(ctx *sql.Context, tableName doltdb.TableName) (*doltdb.Table, error)

GetDoltTableFromContext returns the Dolt table from the context. Returns nil if no table was found.

func GetSchemaName added in v0.12.0 

func GetSchemaName(ctx *sql.Context, db sql.Database, schemaName string) (string, error)

GetSchemaName returns the schema name if there is any exist. If the given schema is not empty, it's returned. If it is empty, uses given database to get schema name if it's DatabaseSchema. If it's not of DatabaseSchema type or the schema name of it is empty, it tries retrieving the current schema used by the context. Defaults to "public" if the context does not specify a schema.

func GetSqlDatabaseFromContext added in v0.12.0 

func GetSqlDatabaseFromContext(ctx *sql.Context, database string) (sql.Database, error)

GetSqlDatabaseFromContext returns the database from the context. Uses the context's current database if an empty string is provided. Returns nil if the database was not found.

func GetSqlTableFromContext added in v0.12.0 

func GetSqlTableFromContext(ctx *sql.Context, databaseName string, tableName doltdb.TableName) (sql.Table, error)

GetSqlTableFromContext returns the table from the context. Uses the context's current database if an empty database name is provided. Returns nil if no table was found.

func Init 

func Init()

Init initializes this package.
