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 [Exchange].[Contacts] WHERE BusinessAddress_City = 'Raleigh'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 [Exchange].[Contacts] (BusinessAddress_City) VALUES ('Raleigh');
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 [Exchange].[Contacts] ([BusinessAddress_City]) SELECT [BusinessAddress_City] FROM [Local_Contacts]You can run a bulk UPATE using a JOIN with a local table.
UPDATE [Exchange].[Contacts] INNER JOIN [Local_Contacts] ON [Local_Contacts].[ItemId] = [Exchange].[Contacts].[ItemId] SET [Exchange].[Contacts].[BusinessAddress_City].[Local_BusinessAddress_City]You can run a bulk DELETE using the IN filter with sub-SELECT query.
DELETE FROM [Exchange].[Contacts WHERE [ItemId] IN (SELECT [ItemId] FROM Local_Contacts)
Execute Stored Procedures
Use the following to run the stored procedure:Call CreateJob('Insert')
