Executing Queries
This section describes how to execute queries using MySQL remoting from any tool that can connect to MySQL.
When executing queries, use a two-part name, in the format:
[<Schema Name>].[<Table Name>]where
- Schema Name is the name of the system schema or user-defined schema. (This is normally the service name.)
- Table Name is the name of the table you are copying data from.
SELECT Statements
To create new records:SELECT * FROM [Parquet].[SampleTable_1] WHERE Column2 = 'Bob'Note: MySQL treats identifiers as case-insensitive, even if the data source supports case-sensitive identifiers. This can be a problem when the database contains multiple tables of the same name in a single schema, because when using MySQL it is not possible to query tables of the same name that only vary by upper or lower case-sensitive (for example, a schema with one table named Account, and a second table named ACCOUNT).
INSERT, UPDATE, and DELETE Statements
To insert, update, or delete a single row of data against a writeable database, use the two-part name. For example:INSERT INTO [Parquet].[SampleTable_1] (Column2) VALUES ('Bob');
Bulk Operations
To perform bulk operations, use syntax similar to the following:You can run a bulk INSERT using a SELECT query in place of a VALUES list.
INSERT INTO [Parquet].[SampleTable_1] ([Column2]) SELECT [Column2] FROM [Local_SampleTable_1]You can run a bulk UPATE using a JOIN with a local table.
UPDATE [Parquet].[SampleTable_1] INNER JOIN [Local_SampleTable_1] ON [Local_SampleTable_1].[Id] = [Parquet].[SampleTable_1].[Id] SET [Parquet].[SampleTable_1].[Column2].[Local_Column2]You can run a bulk DELETE using the IN filter with sub-SELECT query.
DELETE FROM [Parquet].[SampleTable_1 WHERE [Id] IN (SELECT [Id] FROM Local_SampleTable_1)
Execute Stored Procedures
To execute the stored procedure, use:Call CreateJob('Insert')
