SQL Compliance
The CData ADO.NET Provider for Couchbase supports several operations on data, including querying, deleting, modifying, and inserting.
SELECT Statements
See SELECT Statements for a syntax reference and examples.
See Data Model for information on the capabilities of the Couchbase API.
INSERT Statements
See INSERT Statements for a syntax reference and examples, as well as retrieving the new records' Ids.
UPDATE Statements
The primary key Id is required to update a record. See UPDATE Statements for a syntax reference and examples.
UPSERT Statements
An UPSERT updates a record if it exists and inserts the record if it does not. See UPSERT Statements for a syntax reference and examples.
DELETE Statements
The primary key Id is required to delete a record. See DELETE Statements for a syntax reference and examples.
CACHE Statements
CACHE statements allow granular control over the provider's caching functionality. For a syntax reference and examples, see CACHE Statements.
For more information on the caching feature, see Caching Data.
EXECUTE Statements
Use EXECUTE or EXEC statements to execute stored procedures. See EXECUTE Statements for a syntax reference and examples.
Names and Quoting
- Table and column names are considered identifier names; as such, they are restricted to the following characters: [A-Z, a-z, 0-9, _:@].
- To use a table or column name with characters not listed above, the name must be quoted using square brackets ([name]) in any SQL statement.
- Parameter names can optionally start with the @ symbol (e.g., @p1 or @CustomerName) and cannot be quoted.
- Strings must be quoted using single quotes (e.g., 'John Doe').
Transactions and Batching
Transactions are not currently supported.
Additionally, the provider does not support batching of SQL statements. To execute multiple commands, you can create multiple instances and execute each separately.
