Taking a Schema Snapshot

A schema snapshot is a backup of the database files and is used to restore a database if database files get corrupted. To take a snapshot of the enterprisedb schema right-click on the schema in Object Explorer and select Take Snapshot… as shown in Figure 38.

Figure 38. enterprisedb>Take Snapshot…

In Take Snapshot select the default Snapshot Label as shown in Figure 39 and click on OK.

Figure 39. Setting Snapshot Label

A schema snapshot gets created and listed in the Snapshots view, as shown in Figure 40.

Figure 40. Snapshot Schema

Several options are available for a schema. Right-click on the snapshot and select from Export Snapshot, Compare with Default Database, and Export Script as shown in Figure 41. A snapshot may also be renamed or deleted.

Figure 41. Snapshot Options


Setting the Default Schema

The default schema is the schema that is active and associated with a connection worksheet. The enterprisedb schema is the default, as indicated by the blue-green icon in Object Explorer. To make the public schema the default, right-click on public in Object Explorer and select Set Schema as Default as shown in Figure 42.

Figure 42. public>Set Schema as Default

The public schema gets set as the default, as shown by the blue-green icon in Figure 43. The Worksheet1 gets associated with the public schema.

Figure 43. The default schema set to public

We shall be using the enterprisedb as the default schema; for which, set the schema as the default as shown in Figure 44.

Figure 44. Setting back enterprisedb as default schema

The enterprisedb gets set as the default, as shown in Figure 45.

Figure 45. Default schema set to enterprisedb


Comparing Schemas

Schema comparison may be launched from two different toolbar selections: the Database and the Compare drop-downs. A schema snapshot may also be compared, as mentioned earlier, by selecting Compare with Default Database, as shown in Figure 41. Compare with Default Database implies comparison with the default schema and not one of the database instances edb or postgres. To compare the public schema, which is not the default schema, with the default schema or database, right-click on public in the Object Explorer and select Compare with Default Database as shown in Figure 46.

Figure 46. Object Explorer>public>Compare with Default Database

The Compare gets started, as shown in Figure 47. The different object types in the two schemas public and enterprisedb start to get compared.

Figure 47 Compare started

When the Compare gets completed the results are displayed, as shown in Figure 48. Some tables are listed only in the target schema enerprisedb. The script definition for one of the tables, emp, is shown with the Script Definition tab selected.

Figure 48. Compare Completed

The Change Script tab lists the script that may be run to apply the differences in schemas in order to make the target schema the same as the source schema. Applying the differences would mean that the dept, emp and jobhist tables would be dropped from the target schema. The Change Script is run with the button indicated in Figure 49. We won’t be running the Change Script. An individual Change Script is provided for each of the pairs of tables that differ from each other. When a table is selected in the Schema Compare result, the Change Script corresponding to the table gets listed. To apply the differences and make the target schema the same as the source schema, you would run the Change Script.
