## What it does
**SQL Query Description**
=========================

This SQL query retrieves data from multiple tables and performs various calculations to generate a final result set. Here's a breakdown of the query:

### Tables Involved

The query joins data from four tables:

1. `[Metals Header]`: contains metadata about metals.
2. `[RMSFILES#_EGMMP1A0]`: contains additional data related to metals, including production and cost information.
3. `[Metals Not Tracked]`: contains data about metals that are not tracked (e.g., missing or outdated information).
4. `[RMSFILES#_MSPMLVPT]`: contains production data for specific metals.

### Join Order

The query uses a series of left joins to combine data from the tables:

1. First, it joins `[Metals Header]` with `[RMSFILES#_EGMMP1A0]` on the `PartNo` column.
2. Next, it joins the result set with `[Metals Not Tracked]` on the same `PartNo` column.
3. Finally, it joins the previous result set with `[RMSFILES#_MSPMLVPT]` on the `PRDNO` column.

### Calculated Columns

The query calculates two new columns:

1. `Dens`: calculates the density of the metal based on its weight, length, and width. The formula is: `(144/([length]*[Width]))`. If `[Units]` is "SF" (square feet), it returns 1.
2. `IIf([Dens]=0,[IE_Density],[Dens])`: applies an IF function to check if the calculated density (`Dens`) is zero. If it is, it returns `[IE_Density]`, otherwise, it returns the original `Dens` value.

### Final Result Set

The final result set includes all columns from `[Metals Header]`, `[RMSFILES#_EGMMP1A0]`, and `[Metals Not Tracked]`. The calculated columns (`Dens` and its variant) are also included. Finally, it adds a new column `PricePerLB1` which is the result of applying an ITSAZERO function to the `[STDC1]` column.

### Notes

* The SQL query uses various data types (e.g., `[Units]` is assumed to be a string).
* The query assumes that some columns may be null, and it handles these cases using IF functions.
* The use of ITSAZERO and IIf functions suggests that the query is specific to a particular software or system.
