Syntax

The Katzebase SQL dialect (KBSQL) is very similar to T-SQL. Statements do not need to be separated by semicolons or any other terminator; a script can simply list one statement after another. Statements are used to create and alter schemas and indexes; to insert, read, update and delete documents; to manage accounts and permissions; and to run system procedures.
The statements fall into two groups: (1) DML, or data manipulation language, for selecting, inserting, updating and deleting documents, and (2) DDL, or data definition language, for objects such as schemas, indexes, accounts and roles. See DML Glossary and DDL Glossary.


A schema is a container of documents, indexes and other schemas. Schemas are nested and their names are separated with colons, for example WordList:Word is the Word schema inside the WordList schema. A document is a set of field/value pairs. Documents in the same schema do not need to have the same fields.

• Keywords, schema names, field names and function names are not case-sensitive.
• String comparisons with =, != and LIKE are not case-sensitive.
• Strings are enclosed in single (or double) quotes.
• Comments start with -- (until the end of the line) or are enclosed in /* and */.

See Expressions for literals, operators and variables.


Selects all fields from the Word schema.

SELECT * FROM WordList:Word

Selects specific fields from the Word schema for a given Text.

SELECT
    Id, Text, LanguageId
FROM
    WordList:Word
WHERE
    Text = 'Dog'

Inserts two documents using a field list and a values list.

INSERT INTO WordList:Word (Id, Text, LanguageId)
VALUES (1000, 'Sarah', 1), (1001, 'Brightman', 1)

Inserts two documents using field: value pairs. The fields can be different for each document.

INSERT INTO WordList:Word
(Id: 1002, Text: 'Neward', LanguageId: 1),
(Id: 1003, Text: 'Katzebase')

Updates the document with the given Id.

UPDATE
    WordList:Word
SET
    Text = 'Newark',
    LanguageId = 2
WHERE
    Id = 1002

Deletes documents by Text.

DELETE FROM
    WordList:Word
WHERE
    Text = 'Newark'

Creates a schema inside the existing WordList schema.

CREATE SCHEMA WordList:Definitions

Drops a schema with all of its documents, indexes and child schemas.

DROP SCHEMA WordList:Definitions

Creates a composite index.

CREATE INDEX IX_Word_LanguageId_Text
(
    LanguageId,
    Text
) ON WordList:Word

Drops an index.

DROP INDEX IX_Word_LanguageId_Text ON WordList:Word

Lists the connected processes.
