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 [AlloyDB].["alloydb"."schema01".Orders] WHERE ShipCountry = 'USA' 
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 [AlloyDB].["alloydb"."schema01".Orders] (ShipCountry) VALUES ('USA'); 

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 [AlloyDB].["alloydb"."schema01".Orders] ([ShipCountry]) 
SELECT [ShipCountry] FROM [Local_"alloydb"."schema01".Orders] 
You can run a bulk UPATE using a JOIN with a local table.
UPDATE [AlloyDB].["alloydb"."schema01".Orders]  
INNER JOIN [Local_"alloydb"."schema01".Orders] ON [Local_"alloydb"."schema01".Orders].[Id] = [AlloyDB].["alloydb"."schema01".Orders].[Id] 
SET [AlloyDB].["alloydb"."schema01".Orders].[ShipCountry].[Local_ShipCountry] 
You can run a bulk DELETE using the IN filter with sub-SELECT query.
DELETE FROM [AlloyDB].["alloydb"."schema01".Orders WHERE [Id] IN (SELECT [Id] FROM Local_"alloydb"."schema01".Orders) 

Execute Stored Procedures

To execute the stored procedure, use:
Call CreateJob('Insert')
