Comparison Summary
FPDS Query flattens the original nested FPDS XML path 'IDV/contractData/listOfTreasuryAccounts/treasuryAccount/treasuryAccountSymbol/mainAccountCode' into the SQL-ready variable 'content__IDV__contractData__listOfTreasuryAccounts__treasuryAccount__treasuryAccountSymbol__mainAccountCode'.

Use Cases

  • Dictionary lookup and field explanation
  • SQL filtering and grouping
  • Analytical reporting and reusable query building

Common Usage

  • Linking contracts or IDVs to Treasury funding accounts
  • Filtering awards by fund or appropriation code
  • Grouping obligations by account structure for fiscal analysis

Common Mistakes

  • Assuming the code is a human-readable fund name
  • Dropping leading zeros or comparing it as a numeric field

Query Guidance

Use exact-match or grouped comparisons on the code value, and preserve it as text in SQL to avoid truncation or loss of leading zeros. When joining or validating funding data, pair it with other TAS components rather than treating it as a standalone budget identifier.
