Clear prepared statement handle before reconnect by lukasaignerrsg · Pull Request #2364 · microsoft/mssql-jdbc

lukasaignerrsg · 2024-03-25T11:07:14Z

This fix clears the SQLServerPreparedStatement.prepStmtHandle before reconnecting.
The provided interface can also be used for other objects that need to handle reconnecting.

One test fails: PropertyTest.testRetryCount:54->testInvalidPropertyOverBrokenConnection:46 Unexpected error message occurred!Eine bestehende Verbindung wurde softwaregesteuert
durch den Hostcomputer abgebrochen
This might be due to the system being German. The test also failed before the fix.

hi @lukasaignerrsg

thank you for submitting this I have marked this for review

+    private void clearPrepStmtHandle(){
+        prepStmtHandle = 0;
+        cachedPreparedStatementHandle = null;
+        if(getStatementLogger().isLoggable(Level.FINER)){


Minor formatting issue. Should have a space preceeding the initila if statement brace and after the closing brace

Suggested change

if(getStatementLogger().isLoggable(Level.FINER)){

if (getStatementLogger().isLoggable(Level.FINER)){

pls run formatter on all files
