Reading .mdb files with UCanAccess returns column names in all UPPERCASE

梦想的初衷 提交于 2019-12-05 13:53:27
I'm in the middle from migrating from the JDBC-ODBC bridge driver to the UCanAccess driver. In doing this, I'm facing the following problem: The UCanAccess driver returns all columnames in UPPERCASE, but I need them to be CamelCase. Any ideas? Thx! With UCanAccess version 3.x, released in August 2015, ResultSetMetaData now returns the column names in mixed case if that is how they are defined in the database. (That is, they are no longer forced to UPPERCASE.) (Original Answer) Since UCanAccess depends on Jackcess, one possible workaround might be to retrieve the column names from Jackcess

Workaround in UCanAccess for multi-value fields: “incompatible data type in conversion: from SQL type OTHER”?

问题 I am trying to use UCanAccess to query a MS Access .accdb file. Everything works great, except when I query multi-value fields. For example those that have entries in the Row Source of a table field's Lookup tab in design view in MS Access. My code crashes when I try to output the result: ResultSet rslt = stmt.executeQuery("SELECT [singleValue], [multiValue] FROM [TableName];"); int count = 0; while (rslt.next()) System.out.println(count++ + "\t" + rslt.getString(1) + "\t" + rslt.getString(2)
