SQL Conformance

Apache Ignite supports most of the major features of ANSI-99 out-of-the-box. The following table shows Ignite compliance to SQL:1999 (Core).

Feature ID, Name

Support

E011 Numeric data types

Ignite fully supports the following sub-features:

7) If a <scale> is omitted, then a <scale> of 0 (zero) is implicit (6.1 <data type>)

22) NUMERIC specifies the data type exact numeric, with the decimal precision and scale specified by the <precision> and <scale>.

23) DECIMAL specifies the data type exact numeric, with the decimal scale specified by the <scale> and the implementation-defined decimal precision equal to or greater than the value of the specified <precision>.
