----------------------------------
Summary: Couchbase supported data types restriction issues
Key: TEIID-5042
URL: https://issues.jboss.org/browse/TEIID-5042
Project: Teiid
Issue Type: Bug
Components: Misc. Connectors
Affects Versions: 8.12.x-6.4
Reporter: Jan Stastny
Assignee: Steven Hawkins
Priority: Blocker
# Couchbase translator supports only subset of supported datatypes in Teiid:
??All supported type in a Couchbase JSON item: null, String, Integer, Long, Double, BigInteger, BigDecimal, JsonObject, JsonArray??
#* this is too restrictive, why not float? time/date/timestamp? And let the translator to handle conversion in both directions.
# Couchbase leaves out silently the columns with unsupported data types in INSERTs.
#* See the example in bottom of description.
# documentID is (in code) considered String. This is too restrictive. In the code there might be String.valueOf() instead of (String) cast (N1QLUpdateVisitor.java:139). It would help users to use their primary keys (from existing datasets) as document ids in couchbase.
Example:
For a source model DDL:
{code:sql|title=DDL}
CREATE FOREIGN TABLE SmallA (
documentID string PRIMARY KEY,
type string OPTIONS (NAMEINSOURCE '`type`'),
FloatNum float OPTIONS (NAMEINSOURCE '`FloatNum`'),
BigIntegerValue biginteger OPTIONS (NAMEINSOURCE '`BigIntegerValue`'),
StringKey string OPTIONS (NAMEINSOURCE '`StringKey`'),
CharValue string OPTIONS (NAMEINSOURCE '`CharValue`'),
LongNum long OPTIONS (NAMEINSOURCE '`LongNum`'),
DoubleNum double OPTIONS (NAMEINSOURCE '`DoubleNum`'),
ObjectValue string OPTIONS (NAMEINSOURCE '`ObjectValue`'),
ShortValue integer OPTIONS (NAMEINSOURCE '`ShortValue`'),
BigDecimalValue bigdecimal OPTIONS (NAMEINSOURCE '`BigDecimalValue`'),
DateValue string OPTIONS (NAMEINSOURCE '`DateValue`'),
BooleanValue boolean OPTIONS (NAMEINSOURCE '`BooleanValue`'),
TimestampValue string OPTIONS (NAMEINSOURCE '`TimestampValue`'),
ByteNum integer OPTIONS (NAMEINSOURCE '`ByteNum`'),
StringNum string OPTIONS (NAMEINSOURCE '`StringNum`'),
TimeValue string OPTIONS (NAMEINSOURCE '`TimeValue`'),
IntNum integer OPTIONS (NAMEINSOURCE '`IntNum`')
) OPTIONS (NAMEINSOURCE '`dvqe_crud`', UPDATABLE TRUE, "teiid_couchbase:ISARRAYTABLE" 'false', "teiid_couchbase:NAMEDTYPEPAIR" '`type`:''nullSmallA''');
{code}
and query
{code:sql|title=INSERT query}
INSERT INTO Source.SmallA (documentID, StringKey, IntNum, StringNum,DoubleNum, FloatNum,LongNum) VALUES (4, '1', 1, '1',CAST(5.00 AS double),CAST(5.00 AS float), 5);
{code}
there is incorrect source command being pushed to couchbase. The float column is not being pushed at all, no warning appears.
