The following information applies to the StatementInformation parcel.

Flavor Parcel Body Length Parcel Body Fields
169 6 to maximum parcel size Self-defining extensions: Six or more bytes

One or more self-defining extensions are present to convey situation-dependent information. While the extensions may require more than one StatementInformation parcel, an extension will be wholly contained in one parcel. The extensions fall into two types: those that describe one or more items and those with an Information Layout of End-information that end related extensions of the first type.

Each extension begins with the following fields:

Field Length Description
PBTILOUT 2-byte unsigned integer Information Layout identifies the layout of the data following the header, as one of the following:
  1. Full-layout
  2. Limited-layout
  3. Statistic-layout. Used only in responses. For more information, see StatementInformation—Parcel Data.
  4. End-information
  5. Untransformed limited-layout
PBTIID 2-byte unsigned integer Information Id identifies the type of extension. Used only in responses.
  1. Parameter – Used only when DBCAREA Request-processing-option is 'S' (Prepare mode supporting parameterized SQL) (corresponding to the Options parcel [flavor 85] Function 'S' option).
  2. Query
  3. Summary
  4. Identity-column
  5. Stored-procedure-Output
  6. Stored-procedure-resultSet
  7. Estimated-processing
  8. Data-attributes - Describes the data items contained in the request when those attributes are not otherwise known.

For more information, see StatementInformation—Parcel Data.
PBTILEN 2-byte unsigned integer Information Length specifies the length of subsequent data in the extension (does not include the length of the extension header).

Full-layout for Requests

The Full-layout is used for Data-attributes, when DBCAREA Request-processing-option is 'P' (Prepare) or 'B' (Prepare and Execute) (corresponding to the Options parcel [flavor 85] Function 'P', and 'B' options). The following table shows the Full-layout fields. Full-layout field not listed in this table are used only in responses. For more information, see StatementInformation—Parcel Data.

Field Length Description
PBTIFDT 2-byte unsigned integer Specifies the data type of the item. In addition to the data types available for the PrepInfo[X] (flavor 86 or 125) and DataInfo[X] (flavor 71 or 146) parcels. See Data Type for the possible data types. See the table titled, "PBTIFDT Additional Data Types" in StatementInformation—Parcel Data for additional data types that are also supported.
PBTIFMDL 8-byte unsigned integer The total number of bytes of data that might be sent for this item.
PBTIFND 2-byte unsigned integer The total number of digits if the item has a decimal or numeric data type.
PBTIFNID 2-byte unsigned integer The number of interval digits if the item is a temporal data type.
PBTIFNFD 2-byte unsigned integer The number of fractional digits if the item is a decimal data type (or the deprecated temporal types such as time, timestamp, interval ... to second, and interval second).
While only five fields are honored, all full-layout fields must be present. (See the table titled, Full-layout Fields for Responses" StatementInformation—Parcel Data.) Fields with a two-byte length followed by text also of that length must be valid. That is, the length must correspond to the number of bytes of text.

When at least one more byte is present, the first such byte is defined as follows:

Field Length Description
PBTIFTP 1-byte character Set to one of the following EBCDIC characters:
  • 'I' if the item is a stored-procedure IN parameter
  • 'O' if the item is a stored-procedure OUT parameter
  • B' if the item is a stored-procedure INOUT parameter
  • 'U' if the item is not a stored-procedure parameter, or if the information is unavailable
PBTILDOS 2 bytes When Transforms are off for this type of item, the depth of this attribute of the item's structure. A value of zero indicates the item is not a structure or Transforms are not off. Other values indicate the nesting level of the structure.
PBTIFTC 1-byte character Used only in responses. See StatementInformation—Parcel Data.
PBTILUA 2 byte unsigned integer plus the number of bytes specified by that integer When Transforms are off for this type of item, Untransformed Attribute Name consists of the length in bytes of the name of this attribute in the item's structure, followed by that name in characters from the current session character set. If the item is not a structure or Transforms are not off, the length is zero and no name is present. The maximum length of a name may be obtained using the DBCHQE SQL-limits query.
PBTILTDT 2 byte unsigned integer When Transforms are off for this type of item, specifies the data type of the untransformed item. If the item is not a structure or Transforms are not off, the value is zero. In addition to the data types available for the PrepInfo[X] (flavor 86 or 125) and DataInfo[X] (flavor 71 or 146) parcels, which are defined in Data Type. Data Type contains a list of the possible data types. See the table titled, "PBTIFDT Additional Data Types" in StatementInformation—Parcel Data for additional data types that are also supported.

Limited-layout for Requests

The Limited-layout is used for Data-attributes when DBCAREA Request-processing-option is 'E' (Execute) (corresponding to the Options parcel (flavor 85) Function 'E' option). The following table describes the Limited-layout fields specific for requests.

Field Length Description
PBTILDT 2 byte unsigned integer Specifies the data type of the item. In addition to the data types available for the PrepInfo[X] (flavor 86 or 125) and DataInfo[X] (flavor 71 or 146) parcels, which are defined in Data Type. Data Type contains a list of the possible data types. See the table titled, "PBTIFDT Additional Data Types" in StatementInformation—Parcel Data for additional data types that are also supported.
PBTILMDL 8 byte unsigned integer The total number of bytes of data that might be sent for this item.
PBTILND 2 byte unsigned integer The total number of digits if the item has a decimal or numeric data type.
PBTILNID 2 byte unsigned integer The number of interval digits if the item is a temporal data type.
PBTILNFD 2 byte unsigned integer The number of fractional digits if the item is a decimal data type (or the deprecated temporal types such as time, timestamp, interval ... to second, and interval second).

Untransformed limited-layout

The Untransformed limited-layout is used for Data-attributes when DBCAREA Request-processing-option is 'E' (Execute) (corresponding to the Options parcel (flavor 85) Function 'E' option). The following table describes the Untransformed limited-layout fields specific for requests.

Field Length Description
PBTIUDT 2 byte unsigned integer Specifies the data type of the item. In addition to the data types available for the PrepInfo[X] (flavor 86 or 125) and DataInfo[X] (flavor 71 or 146) parcels, which are defined in Data Type. Data Type contains a list of the possible data types. See the table titled, "PBTIFDT Additional Data Types" in StatementInformation—Parcel Data for additional data types that are also supported.
PBTIUMDL 8 byte unsigned integer The total number of bytes of data that might be sent for this item.
PBTIUND 2 byte unsigned integer The total number of digits if the item has a decimal or numeric data type.
PBTIUNID 2 byte unsigned integer The number of interval digits if the item is a temporal data type.
PBTIUNFD 2 byte unsigned integer The number of fractional digits if the item is a decimal data type (or the deprecated temporal types such as time, timestamp, interval ... to second, and interval second).

When at least one more byte is present, the first such additional is defined as follows:

Field Length Description
PBTIUTDT 2 byte unsigned integer When Transforms are off for this type of item, specifies the data type of the untransformed item. If the item is not a structure or Transforms are not off, the value is zero. In addition to the data types available for the PrepInfo[X] (flavor 86 or 125) and DataInfo[X] (flavor 71 or 146) parcels, which are defined in Data Type. See the table titled, "PBTIFDT Additional Data Types" in StatementInformation—Parcel Data for additional data types that are also supported.
PBTIUAT 2 byte unsigned integer plus the number of bytes specified by that integer Array Element Type Name consists of the length in bytes of the name followed by that name in characters from the session character set. If the type is not an array, the length is zero and no name is present. The maximum length of a name may be obtained using the DBCHQE SQL-limits query.
PBTIUAD 2 byte unsigned integer plus two lists, each containing the number of 4 byte unsigned entries specified by that integer Array Number of Dimensions consists of the number of dimensions in the array followed by two lists: the first specifies the number of elements in that dimension of the array; the second specifies the lower bound for that dimension of the array. If the type is not an array, the number of dimensions is zero and the two lists are not present.

End-information layout

The End-information layout indicates there are no more items for the current information (Data-attributes). No data exists for End-information.
