Executing Queries
This section describes how to execute queries using MySQL remoting from any tool that can connect to MySQL.
When executing queries, you use a two-part name format, as shown below,
[<Schema Name (normally but not always the service name)>].[<Table Name>]where
- Schema Name is the name of the system schema or user-defined schema.
- 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 that if the data source supports case-sensitive identifiers, it is not possible to query tables of the same name that only vary by upper or lower case-sensitive (ex: Account and ACCOUNT in the same schema). This is because MySQL treats identifiers as case-insensitive, so multiple tables of the same name in a single schema are fundamentally incompatible with the MySQL protocols.
INSERT, UPDATE, and DELETE Statements
To insert, update, or delete a single row of data (that is, not a batch of records), you need to use the two-part name. For example:INSERT INTO [MongoDB].[[CData].[Sample].Customers] (Country) VALUES ('US');
Bulk Operations
To perform bulk operations, you can 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
Use the following to run the stored procedure:Call CreateJob('Insert')
