splitSql splits a string containing multiple SQL statements into a vector of SQL statements
The SQL string to split into separate statements
A vector of strings, one for each SQL statement
This function is needed because some DBMSs (like ORACLE) do not accepts multiple SQL statements being sent as one execution.
splitSql("SELECT * INTO a FROM b; USE x; DROP TABLE c;") #>  "SELECT * INTO a FROM b" "USE x" "DROP TABLE c"
