Java 8 and later: JDBCType & SQLType With improvements in the API’s, as of Java 8 and JDBC 4.2, we have JDBCType and SQLType, and in the same spirit as some of the other examples can be simply used as follows: String typeName = JDBCType.valueOf(-5).getName(); But of course, why using the numeric types to begin … Read more
Original Post: They’ve since moved from Google Code to BitBucket. Here’s the BitBucket Repo: https://bitbucket.org/xerial/sqlite-jdbc Update 8-13-2015: Now they’re off to GitHub: https://github.com/xerial/sqlite-jdbc I’ve left the bitbucket link because there is a wealth of project information there, even though the code has moved to git hub.
pass Statement.RETURN_GENERATED_KEYS in prepareStatement() along with your query. And then use getGeneratedKeys() of PreparedStatement to get the ResultSet containing your inserted auto_incremented_id. String query=”Insert INTO Table_A(name, age) (?, ?)”; //String query=”Insert INTO Table_A(name, age) (‘abc’,’123′ )”;//Doesn’t escape PreparedStatement prest; prest = con.prepareStatement(query, Statement.RETURN_GENERATED_KEYS); prest.setString(1,”abc”); prest.setInt(2,123); prest.executeUpdate(); //prest.executeUpdate(query, PreparedStatement.RETURN_GENERATED_KEYS); Throws an error //prest.executeQuery(); Throws an error … Read more
Seems like the same issue as this one: jtds-driver-not-working-for-sql-sever-2008r2-and-denali-native-sspi-library-not You should drop the appropriate ntlmauth.dll file from the JTDS download package into your JRE bin folder. If you’re running on a 64bit Windows machine: This 32bit DLL: Downloads >>> jtds-1.3.0-dist.zip >>> x86 >>> SSO >>> ntlmauth.dll Goes here in this 32bit JRE location: C:\Program Files … Read more
Since the text type is not a part of the SQL standard there is no official JPA way I guess. However, the text type is quite similar to varchar, but without the length limit. You can hint the JPA implementation with the length property of @Column: @Column(length=10485760) private String description; Update: 10 MiB seems to … Read more
This indicates a bad DB design. The user shouldn’t need to know about the column names. Create a real DB column which holds those “column names” and store the data along it instead. And any way, no, you cannot set column names as PreparedStatement values. You can only set column values as PreparedStatement values If … Read more
It seems the mysql connectivity library is not included in the project.

http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html spring.jpa.hibernate.naming.strategy is not a supported property for Spring JPA implementation using Hibernate 5. Use the below property in application.properties spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
Option 1 is closest: double d = rs.getDouble(1); if (rs.wasNull()) { // do something } else { // use d } It’s not very nice, but that’s JDBC. If the column was null, the double value is considered “bad”, so you should check using wasNull() every time you read a primitive that is nullable in … Read more
First: check the case in which you type tables’ names. It’s very important. word_types and WORD_TYPES are two different tables. Second: If you want to check if table exists and if it doesn’t then create one, I recommend you to use the following example: CREATE TABLE IF NOT EXISTS TEST(ID INT PRIMARY KEY, NAME VARCHAR(255));
