Known Issues

The following is a list of issues, including those attributed to third-party products, known to exist in this release line at the time of the current release.

General known issues

Known Issue Issue ID
Toad's help cannot be opened from an installation path that contains Unicode characters. 72966

If you check "Indexes" on the Scripts tab for snapshots, then the primary key for the snapshot will be included in the script, even though the CREATE MATERIALIZED VIEW statement implicitly creates this primary key.

Toad currently does not differentiate between indexes created explicitly on the snapshot and indexes created automatically when the snapshot is created.

Workaround: If you are running the generated script to recreate the snapshot, then you can simply ignore the error that occurs when the script tries to recreate the primary key index for the snapshot. If you do not normally create indexes on snapshots, then you can uncheck "Indexes" when generating the snapshot script.


If you use 11g Oracle ODP.NET client or any other client that does not have the oci.dll in the BIN directory, Toad has the following problems:

  1. Client shows as invalid
  2. Client version is not detected
  3. As a result of #2, columns of the following datatypes are not shown in the Schema Browser table data: CLOB, BLOB, NCLOB, XMLTYPE, TIMESTAMP, INTERVAL, BINARY_DOUBLE, and BINARY_FLOAT


If there is an exception during debugging on a 10Gr2 or greater database, REFCURSOR output and DBMS output will not be available when debugging is completed. This is due to the target session not being available.

Workaround: To see REFCURSOR output and DBMS output, execute the procedure without the debugger.



While Toad supports LDAP connectivity, some features of Toad depend on tnsnames.ora file to operate correctly, such as Toad Script Runner (TSR).


Schema Browser

Sometimes after pressing "Compile invalid objects", you may get ORA-20000, ORA-06512, or ORA-06512 errors. This could mean that you do not have the privileges to compile the object, but it also happens when the schema contains a package body that does not have an associated spec.

Workaround: Look in the schema that you are trying to compile to see whether there are any orphan package bodies. If it is your own schema, then do:select * from user_objects o1 where object_type = ''PACKAGE BODY'' and not exists (select ''x'' from user_objects o2 where o2.object_name = o1.object_name and o2.object_type = ''PACKAGE'') Then drop any orphan package bodies that are found.



An access violation error may display when you close Toad in a Citrix XenApp environment.



Constraint scripts from Export DDL do not contain the "using index" or "tablespace" clause.


Data Modeler:

  • Generation of HTML reports of large diagrams may fail during generation of an image of the ER Diagram.
  • Comparison of large models may consume too much memory.

Data Grids known issues

Known Issue Issue ID

You may receive an "ORA-00902 invalid datatype" error when editing an object, nested table, or varray data if you have redefined the data type for that data during the current session.

Workaround: If you redefine an object type, nested table, or varray and then need to edit data in a table based on that type, end your current connection and begin a new one.


Full table data is not displaying in the live data grid (results from F9) if the data contains "zero" characers (ACII 0). In this case, all data after the zero character will not show in the grid.

Workaround: Double click on the data cell in the data grid to view full contents of data in a popup editor.


Code Analysis known issues

Known Issue Issue ID
Saving results to a database: When dealing with nested procedures, Code Analysis can only insert run data from procs one level deep. N/A

Saving PL/SQL results to a database may fail or save invalid data to the database for invalid PL/SQL objects.

Workaround: To ensure PL/SQL results are saved to the database correctly, verify the validity of all objects before running Code Analysis.


Editor known issues

Known Issue Issue ID

Toad errors when you query on a field of Oracle collection types.

Workaround: Execute using SQL*Plus.


When spooling to an unpinned output window, the window becomes unresponsive and errors are given when Toad is closed ("Canvas does not allow drawing").

Workaround: Keep the output window pinned.


If you use a non fixed-width font, the results are misaligned in the of Script Output tab in Editor after executing a SQL script.

Workaround: Go to Options | Scripts and select a fixed-width font for script output.


Session Browser known issues

Known Issue Issue ID
The Program name in the Session Browser may be blank or may be the full path to the executable instead of just the executable name. This depends on the Oracle client, not on Toad. N/A

In RAC databases, version (and possibly other 10.1 versions), the query used to populate the "Current Statement" in the Session Browser fails with the following error: Runtime error occurred: 12801 (ORA-12801: error signaled in parallel query server PZ99, instance <instance name> ORA-01008: not all variables bound) This problem does not occur in Non-RAC environments.

Workaround: Clear the "Use RAC Views" checkbox, and log into the appropriate instance of the database, if necessary.


Team Coding known issues

Known Issue Issue ID

Creating a new revision or attempting to force a check-in to Visual Studio Team Services may result in a "404: Not Found" error. The current version of Team Foundation Server used by Visual Studio Team Services compares the source being uploaded with the source already in the repository. If the source has not changed, it may incorrectly return an error rather than allowing the forced revision. This appears to be a Microsoft issue. As a result, these two commands may fail.


When using the Team Foundation Server internal client and Team Foundation Server 2012 or 2013 alternate Team Project Collections, workspaces created outside of Toad are not visible from within Toad. A workspace may be created from Toad by clicking the ‘New’ button during the Team Foundation Server log in.

This is not an issue when using the Team Foundation Server external client.

Team Coding is disabled for mixed-case object names. N/A

With CVS, Toad may fail to retrieve the list of projects for you to select from in the CVS browser or in the Code Control Groups configuration.

Workaround: See "Missing CVS\Entries File Error" in the online help.

Team Coding and Clearcase: Dynamic Views are not supported via SCC interface. Snapshot Views must be used instead. (Rational case ID v0830629, Rational Defect # CMBU00053934) N/A

Unicode known issues

Known Issue Issue ID

The following features in Toad do not support Unicode:

  • ASM Manager
  • Export File Browser
  • Hex Editor

In addition, Java itself does not allow Unicode class names or file names. This is relevant to the Java Manager, Editor, and Schema Browser.


Editor options to highlight object names may not work for object names that contain Unicode characters.

Script Execution in Editor: Error offset can be incorrect when running scripts with multi-byte object names. N/A
XML (Plain) format creates bad XML if Unicode string values and Unicode column names are exported through Export Dataset. N/A

Import mapping for Unicode characters is incorrect if the characters are not a fixed width (such as Korean).

In Team Coding, objects with Unicode contents are supported, objects with Unicode names are not. Supported Version Control Providers do not support Unicode names. N/A

High DPI known issues

Known Issue Issue ID


(Affects Windows Server 2019 only)

Toolbar button images may disappear when you mouse over them if the "High DPI scaling override" option is set to "System (Enhanced)" in the Windows file properties dialog for Toad.exe


Third-party known issues

Known Issue Issue ID


(Affects the 64-bit version of Toad only)

If IE9 is installed, clicking a link in the Help file may crash Toad 64-bit, even if IE9 is not the default browser.

  • Internet Protocol Version 6 (IPv6) is being adopted by the US Federal Government and industries around the world. In its most basic format, the new protocol uses 128-bit addresses instead of 32-bit addresses, which are used by the current IPv4 to route packets over the Internet. Toad for Oracle features, such as FTP, access the Internet through third-party vendors that are IPv6 compliant, such as /nSoftware's IP*Works. For access to Web sites by way of the Toad Online window, Toad simply invokes the user-defined or default Web browser.
