<p>I'm getting an error with this query:</p> <pre><code> MERGE INTO edw_clctns_equip_dim d USING psa_equipment_status_history ON ( dw_equipment_id = TO_NUMBER (d.clctns_equip_source_id) AND d.active_ind = 'Y') WHEN MATCHED THEN UPDATE SET clctns_initial_status_date = (SELECT MIN (effective_date) FROM psa_equipment_status_history WHERE dw_equip_status_type_id IN ( SELECT dw_equip_status_type_id FROM psa_equipment_status_type WHERE equipment_status_code = '100') AND current_flag = 'Y' AND iud_flag <> 'D' AND dw_equipment_id = TO_NUMBER (d.clctns_equip_source_id)) </code></pre> <p>I can use the simple update query, but it is taking way too long. Does the merge statement help?</p> <pre><code>Update EDW_CLCTNS_EQUIP_DIM d Set CLCTNS_INITIAL_STATUS_DATE = ( SELECT MIN(EFFECTIVE_DATE) FROM PSA_EQUIPMENT_STATUS_HISTORY WHERE DW_EQUIP_STATUS_TYPE_ID In ( Select DW_EQUIP_STATUS_TYPE_ID From PSA_EQUIPMENT_STATUS_TYPE Where EQUIPMENT_STATUS_CODE = '100' ) AND CURRENT_FLAG = 'Y' AND IUD_FLAG<>'D' AND DW_EQUIPMENT_ID=to_number(d.CLCTNS_EQUIP_SOURCE_ID) ); </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
