You can export an individual table using the Export Table assistant.
To export a table:
Below is an example of what the Export Table window looks like. There may be different options based on what database type the table is exported from.
You can export tables in one of these formats: CSV, HTML, SQL, XML, Excel, or JSON.
For the SQL and XML formats, you can choose to export the DDL and the table data; the other formats only export table data.
You can control whether to use delimited identifiers and/or qualified names by default in the DDL and INSERT statements generated for the SQL format, and you can override the defaults in the Export dialog for a single export operation.
Excel export do not support formatted date, time or timestamp. To get the correct date format in Excel you either have to export dates as text (check the Export Date/Time as Text) or set the format explicitly in Excel.
The destination can be one of:
You can use the export assistant to export Binary/BLOB and CLOB data. You enable this by choosing File as the data format for Binary/BLOB and/or CLOB data. Optionally, you can specify the directory or filename pattern for the data files. If you do not specify a directory or filename pattern, the operating system's default directory for temporary files (e.g. C:\TEMP or /tmp) is used.
A pattern is a path with fixed and variable parts, where the variable parts are expressed as DbVisualizer variables, e.g. C:\Users\wti\exp\${dbvis-date}$\${COUNTRY_NAME}$.txt. You can select variables to insert at the current caret position in the path field from the dropdown. The variables that can be used are the predefined DbVisualizer variables plus variables for each column in the table, e.g. ${COUNTRY_NAME}$ in the example above. Another special variable that can be helpful here is ${dbvis-column-name}$. If a table has multiple BLOB or CLOB columns, you can use it in the pattern to export the columns to separate files, e.g. C:\Users\wti\exp\${dbvis-column-name}$.txt. All variables that can be used are listed in the menu that is displayed when you click the blue arrow to the right of the field. You can select a variable from the menu to insert it in the pattern field at the caret position.
The data for each individual value of this type is then exported to a separate file and a DbVisualizer variable referencing the file is inserted in the main export file.
Example:
Assume you have a table with multiple pictures and want them exported in individual files, for instance a BOOK table with the columns ISBN and pictures of FRONT and BACK:
ISBN FRONT BACK

0345391810 BINARY, 4,998 Bytes BINARY, 4,998 Bytes
If you specify the output as D:\tmp\${ISBN}$-${dbvis-column-name}$.png, you will get the following image files:
