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 [MongoDB].[[CData].[Sample].Customers] WHERE Country = 'US' 

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 [MongoDB].[[CData].[Sample].Customers] (Country) VALUES ('US'); 

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 [MongoDB].[[CData].[Sample].Customers] ([Country]) 
SELECT [Country] FROM [Local_[CData].[Sample].Customers] 

You can run a bulk UPATE using a JOIN with a local table.

UPDATE [MongoDB].[[CData].[Sample].Customers]  
INNER JOIN [Local_[CData].[Sample].Customers] ON [Local_[CData].[Sample].Customers].[_id] = [MongoDB].[[CData].[Sample].Customers].[_id] 
SET [MongoDB].[[CData].[Sample].Customers].[Country].[Local_Country] 

You can run a bulk DELETE using the IN filter with sub-SELECT query.

DELETE FROM [MongoDB].[[CData].[Sample].Customers WHERE [_id] IN (SELECT [_id] FROM Local_[CData].[Sample].Customers) 

Execute Stored Procedures

To execute the stored procedure, use:

Call CreateJob('Insert')
