# SQL Command Unit Batch

The command to determine unit batches from HEB data sources is a SQL statement that is structured according to the following syntax:

```
SELECT
[TPB_VW_PROC_EXEC].[USERPROCEDUREID] AS [LotNumber]
,[TPB_VW_PROC_EXEC].[STARTTIME] AS [Start]
,[TPB_VW_PROC_EXEC].[ENDTIME] AS [End]
,[TPB_VW_EQ].[NAME] AS [BatchID]
,[TPB_VW_EQ].[FULLNAME] AS [Namespace]
,[TPB_VW_PROC_EXEC].[DURATION] AS [Duration]
,[TPB_VW_PROC_EXEC].[PROCEDUREEXECUTIONID] AS [ProductID]
,[TPB_VW_EQ].[EQUIPMENTLEVELNAME] AS [UnitBatchID]
FROM
[ProcedureAnalyst].[pa].[TPB_VW_PROC_EXEC],
[ProcedureAnalyst].[pa].[TPB_VW_PROC],
[ProcedureAnalyst].[pa].[TPB_VW_EQ]
WHERE
[ProcedureAnalyst].[pa].[TPB_VW_PROC_EXEC].[PROCEDUREID]=[ProcedureAnalyst].[pa].[TPB_VW_PROC].[PROCEDUREID] AND
[ProcedureAnalyst].[pa].[TPB_VW_PROC_EXEC].[EQUIPMENTID]=[ProcedureAnalyst].[pa].[TPB_VW_EQ].[EQUIPMENTID] AND
[ProcedureAnalyst].[pa].[TPB_VW_EQ].[EQUIPMENTLEVELNAME]= 'Unit' AND
[ProcedureAnalyst].[pa].[TPB_VW_PROC].[PROCEDURELEVELNAME] = 'Unit Procedure' AND
[ProcedureAnalyst].[pa].[TPB_VW_PROC_EXEC].[STARTTIME] >= <<TS_From>> AND
[ProcedureAnalyst].[pa].[TPB_VW_PROC_EXEC].[ENDTIME] <= <<TS_To>>
```

This SQL command contains both keywords and alias names.

The keywords ***<\<TS\_From>>*** and ***<\<TS\_To>>*** are enclosed in double angle brackets. At runtime, they are replaced with the start time and end time of the query, respectively, to limit the query time period.

The alias names appear in square brackets to the right of the word "AS". When editing this command, note that the content of the columns assigned to the alias names \[Start] and \[End] are timestamp values.

{% hint style="info" %}
The keywords **<\<TS\_From>>** and **<\<TS\_To>>** and the alias names in the command do not need to be modified.
{% endhint %}
