---------------------------------------
Summary: ODBC: Escape functions: Ensure that escape sequence token
is parsed correctly irrespective of whitespaces.
Key: IGNITE-3738
URL: https://issues.apache.org/jira/browse/IGNITE-3738
Project: Ignite
Issue Type: Task
Components: odbc
Affects Versions: 1.7
Reporter: Vladimir Ozerov
Assignee: Andrew Mashenkov
Fix For: 1.8
The following escape sequences must be supported and parsed correctly:
1) {fn X}
2) { fn X}
3) { fn X}
4) { \n X}
Etc. That is, irrespective of whitespaces, everything must be parsed correctly.
I propose to rely on {{Character.isWhitespace}}, not on regexp. That is, once {
is found, we should simply skip all following whitespaces, then get the token,
then possibly skip more whitespaces.
