SQL Worksheet and Query Client for Oracle / MySQL and MSSQL Databases
MSSQL is only implemented for Android 5 and higher, not for Android 4.4.
This app should be used in a secure network like a vpn network or a local secured network, because the traffic isn't encrypted !
There is a problem (ORA-12705) with NLS (Oracle and thin client) for some countries. if your phone or tablet has a language (for example Cyrillic) , that is not supported, you can try to change the locale in the settings-window to "US" (checkbox for a US default connection). it seems to be a oracle express problem, on tests with oracle standard/enterprise databases i do not have this connect errors.
this oracle sql client uses a direct thin v8 connection for Android 4.4 nd lower and a direct thin v11 connection for android 5 and higher to your database ! if your db-admin doesn't allow you direct thin connections (v8 or v11) from a Client, this app can't connect to your oracle database !
