Subject: [OASIS Issue Tracker] (ODATA-1017) Extend FilterExpressionRestrictions with "Pattern"


     [ https://issues.oasis-open.org/browse/ODATA-1017?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Pizzo updated ODATA-1017:
---------------------------------

    Proposal: 
Add new allowed value

  <Record>
    <PropertyValue Property="Value" String="SearchExpression" />
    <Annotation Term="Core.Description" String="String property can be used as first operand in startswith, endswith, and contains clauses" />
  </Record>

for properties representing character large objects.

> Filter expression restrictions where introduced in ODATA-816 to express restricted filter capabilities on individual properties that can only be used in equality comparison or interval comparison.
> Another important class of restrictions is for operators on character large objects (CLOB, NCLOB, TEXT). Many data stores only support null check and pattern matching on columns of this type and do not support equality or greater-than comparison.
