ERROR: Published UNO API must not be changed incompatibly! tdf#51779

[Devansh Varshney <varshney.devansh614@xxxxxxxxx>]

Hi,

Currently I have made changes regarding the support of the SQL INTERVAL and now working to get it fit with the XRow and the XColumn in the https://github.com/LibreOffice/core/blob/4695d84b78d04af6682961732ae92655e03f49eb/connectivity/source/commontools/FValue.cxx#L2133 (PatchSet 5 - https://gerrit.libreoffice.org/c/core/+/165012/5 is related to this)

But, I am now at this page - https://wiki.documentfoundation.org/Development/Incompatible_UNO_API_Changes

As after making the entry in the offapi/com/sun/star/sdb/XColumn.idl and the offapi/com/sun/star/sdbc/XRow.idl  I got this after running the make -

Gerrit     -    https://gerrit.libreoffice.org/c/core/+/165012

So, my question is should I go and make changes after the consensus or should I not make these changes as this will disrupt the backward compatibility and prevent disruptions for existing users and extensions.

This is what I have added in the offapi/com/sun/star/sdb/XRow.idl

/** gets the value of a column in the current row as an SQLINTERVAL value.

@param columnIndex

the first column is 1, the second is 2,

@returns

the column value; if the value is SQL NULL, the result is a default-constructed SqlInterval

@throws SQLException

if a database access error occurs.

*/

com::sun::star::util::SqlInterval getSqlInterval([in]long columnIndex)

raises (SQLException);

and the offapi/com/sun/star/sdbc/XColumn.idl 

/** gets the value of a column in the current row as an SQL INTERVAL value.

@returns

the column value; if the value is SQL NULL, the result is a default-constructed SqlInterval

@throws SQLException

if a database access error occurs.

*/

com::sun::star::util::SqlInterval getSqlInterval()

raises (com::sun::star::sdbc::SQLException);

Thanks and Regards,

Devansh
