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 [Workday].[[CData].[Human_Resources].Workers] WHERE Legal_Name_Last_Name = 'Morgan'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 [Workday].[[CData].[Human_Resources].Workers] (Legal_Name_Last_Name) VALUES ('Morgan');
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 [Workday].[[CData].[Human_Resources].Workers] ([Legal_Name_Last_Name]) SELECT [Legal_Name_Last_Name] FROM [Local_[CData].[Human_Resources].Workers]You can run a bulk UPATE using a JOIN with a local table.
UPDATE [Workday].[[CData].[Human_Resources].Workers] INNER JOIN [Local_[CData].[Human_Resources].Workers] ON [Local_[CData].[Human_Resources].Workers].[Id] = [Workday].[[CData].[Human_Resources].Workers].[Id] SET [Workday].[[CData].[Human_Resources].Workers].[Legal_Name_Last_Name].[Local_Legal_Name_Last_Name]You can run a bulk DELETE using the IN filter with sub-SELECT query.
DELETE FROM [Workday].[[CData].[Human_Resources].Workers WHERE [Id] IN (SELECT [Id] FROM Local_[CData].[Human_Resources].Workers)
Execute Stored Procedures
Use the following to run the stored procedure:Call CreateJob('Insert')
