I'm writing a program utilizing JDBC that will check if a table exists and create it if it doesn't.
I was planning to include the following:
String query = (some query);
int createIfNotExists = connection.createStatement().executeUpdate(query);
But it's not allowing me to use "IF" in my SQL query. Why is this? Do I need to use some different type of driver? Or is IF just not allowed with JDBC? Has anyone dealt with this before, and how'd you handle it?
DatabaseMetaData md = connection.getMetaData();
String query = "";
boolean exist=false
ResultSet rs = md.getTables(null, null, "table_name", null);
while (rs.next()) {
exist = True ;
}
if(!exist){
query="CREATE TABLE table_name ...";
connection.createStatement().executeUpdate(query);
}
