Transaction Formats

AQS Transaction Formats

This page describes the input transaction formats for AQS data.

The first field of all input formats is the transaction type, i.e., "RD", which indicates the type of data in the record. (Valid transaction types are listed below.) The second field is the Action Indicator, i.e. "I" for insert, "U" for update, and "D" for delete, which indicates the requested database manipulation action. The next block of fields is the primary key information which usually includes the State Code (or Tribal Indicator), County Code (or Tribal Code), Site ID, Parameter, and POC. It may also include assessment type or agency identifier. The combination of key fields serves to uniquely identify the record.

All transactions are pipe delimited ("|"). If you need to report a given field as null, place two delimiters back to back ("||"). Text fields should not be enclosed with single or double quotation marks. A delimiter does not need to follow the final field in a record, so there will always be one less delimiter than fields for the given transaction type.

When changing a record, populate all the required fields. Once the required fields are included, it is not necessary to supply non-required information, and you also do not need to pad the transaction with delimiters.

Example: You need to only update probe height (which is the 13th field in the "Monitor Basic" transaction) and you can ignore empty trailing field delimiters in that row as long as none of these fields are required. A complete transaction would look like:

MA|U|01|005|0002|88502|5||||||2||||||||||||||||20060312|

But all that is required is this:

MA|U|01|005|0002|88502|5||||||2

Please Note the formatting rules described in this document are a "quick reference" and not comprehensive. For the full description of how AQS will validate your input, please refer to the Data Coding Manual (PDF).
