问题 I am working on a legacy project that uses jTDS to connect to SQL server. The client wants us to support SQL Server 2012 AlwaysOn. one key requirement is the ability of our application to automatically reconnect to secondary server in event of failover. unfortunately, jTDS 3.0 does not support AlwaysOn.

问题 I am using android studio to develop an application and using Azure Sql Server to host my database. The problem is I was able to connect to my database on SQL server but it has an error of Object not found in my database. I found out that it might be connecting to my master database instead of the database I want it to connect to.

A SQL command fails to Excute with java.sql.SQLException: I/O Error: Read timed out (I can live with that, if it just happens twice a day or so) But from that moment on the connection seems to be wasted without the pool recognizing it, as I continously receive java.sql.SQLException: Invalid state, the Connection object is closed.

问题 Currently, the jTDS JDBC driver (1.2.5) against Microsoft SQL Server 2008 appears to incorrectly report the data type for DATE columns as NVARCHAR. It probably behaves the same for both earlier versions of jTDS and SQL Server (2005, 2000) Are there any workarounds for this that don't require switching to a different driver (for example Microsoft's own driver) or patching the jTDS driver? Also I would like to avoid having to perform queries against the data dictionary (INFORMATION_SCHEMA

问题 When I'm trying to get column type from ResultSetMetaData with method getColumnTypeName for types date and time(x) , I'm getting nvarchar . For other types seems it works fine. Is this a bug? With ResultSet getString("TYPE_NAME") it seems ok. I'm running on MSSQL2008 @a_horse_with_no_name ResultSetMetaData I'm getting when executing query. In that case I haven't any tables. Here is the code snippet if (resultType == ResultMappingType.QUERY){ // For Query Statement statement = con
