Fixed-WidthProperties
OptionsRequired/Optional Description
NullCharacter:Text/Binary
Required
Indicates the character representing a null value in the file.This can be any valid character in the file code page, or anybinary value from 0 to 255. For more information aboutspecifying null characters, see Null Character Handling.
Repeat NullCharacter
Optional
If selected, the PowerCenter Server reads repeat NULLcharacters in a single field as a single NULL value. If youdo not select this option, the PowerCenter Server reads a
single null character at the beginning of a field as a nullfield. Important: For multibyte code pages, Informaticarecommends that you specify a single-byte null character if you are using repeating non-binary null characters. Thisensures that repeating null characters fit into the columnexactly.For more information about specifying null characters, seeNull Character Handling.
Code Page RequiredSelect the code page of the fixed-width file. The defaultsetting is the client code page.
Number of Initial Rows toSkip
Optional
The PowerCenter Server skips the specified number of rows before reading the file. Use this to skip header rows.One row may contain multiple rows. If you select the LineSequential File Format option, the PowerCenter Serverignores this option.You can enter any integer from zero to 2147483647.
Number of Bytes to Skip
BetweenRecords
Optional
The PowerCenter Server skips the specified number of bytes between records. For example, you have an ASCIIfile on Windows with one record on each line, and acarriage return and line feed appear at the end of each line.If you want the PowerCenter Server to skip these twosingle-byte characters, enter 2.If you have an ASCII file on UNIX with one record for

DelimitedFile
PropertiesOptions
Required/Optional Description
Delimiters Required
Character used to separate columns of data in the sourcefile. Use the Browse button to the right of this field to entera different delimiter. Delimiters can be either printable orsingle-byte unprintable characters, and must be differentfrom the escape character and the quote character (if selected). You cannot select unprintable multibyte
characters as delimiters. The delimiter must be in the samecode page as the flat file code page.
OptionalQuotes
Required
Select None, Single, or Double. If you select a quotecharacter, the PowerCenter Server ignores delimitercharacters within the quote characters. Therefore, thePowerCenter Server uses quote characters to escape thedelimiter.For example, a source file uses a comma as a delimiter andcontains the following row: 342-3849, 'Smith,
Jenna', 'Rockville, MD', 6.
If you select the optional single quote character, thePowerCenter Server ignores the commas within the quotesand reads the row as four fields.If you do not select the optional single quote, thePowerCenter Server reads six separate fields.When the PowerCenter Server reads two optional quotecharacters within a quoted string, it treats them as one quotecharacter. For example, the PowerCenter Server reads thefollowing quoted string as I'm going tomorrow:
2353, 'I''m going tomorrow.', MDAdditionally, if you select an optional quote character, thePowerCenter Server only reads a string as a quoted string if the quote character is the first character of the field.Note: You can improve session performance if the sourcefile does not contain quotes or escape characters.
Code Page RequiredSelect the code page of the delimited file. The defaultsetting is the client code page.
EscapeCharacter
Optional
Character immediately preceding a delimiter characterembedded in an unquoted string, or immediately precedingthe quote character in a quoted string. When you specify anescape character, the PowerCenter Server reads thedelimiter character as a regular character (called escapingthe delimiter or quote character).Note: You can improve session performance for mappingscontaining Sequence Generator transformations if thesource file does not contain quotes or escape characters.
Remove
EscapeCharacterFrom Data
Optional This option is selected by default. Clear this option toinclude the escape character in the output string.
TreatConsecutiveDelimiters asOne
Optional
By default, the PowerCenter Server reads pairs of delimiters as a null value. If selected, the PowerCenterServer reads any number of consecutive delimitercharacters as one.For example, a source file uses a comma as the delimitercharacter and contains the following record: 56, , , JaneDoe. By default, the PowerCenter Server reads that recordas four columns separated by three delimiters: 56, NULL,NULL, Jane Doe. If you select this option, the PowerCenterServer reads the record as two columns separated by one

Table A-13 describes the Writers settings on the Mapping tab (Targets node):
delimiter: 56, Jane Doe.
Number of Initial Rows toSkip
OptionalThe PowerCenter Server skips the specified number of rowsbefore reading the file. Use this to skip title or header rowsin the file.
For relational targets, choose Relational Writer or File Writer.When the target in the mapping is a flat file, an XML file, a SAP
BW target, or MQ target, the Workflow Manager specifies thenecessary writer in the session properties.When you choose File Writer for a relational target you can usean external loader to load data to this target. For moreinformation, see External Loading.When you override a relational target to use the file writer, theWorkflow Manager changes the properties for that targetinstance on the Properties settings. It also changes theconnection options you can define on the Connections settings.After you override a relational target to use a file writer, definethe file properties for the target. Click Set File Properties and
choose the target to define. For more information, seeConfiguring Fixed-Width Properties and Configuring DelimitedProperties.

Properties Settings for Relational Targets
You can configure the writer and object instance attributes for a relational target.
Figure A-16 displays the Properties settings on the Mapping tab for relational targets:
Table A-15 describes the Properties settings on the Mapping tab for relational targets:
You can choose Normal or Bulk.If you select Normal, the PowerCenter Server
loads targets normally.You can only choose Bulk when you load toSybase, Oracle, or Microsoft SQL Server. If youselect Bulk for a Sybase, Oracle, or MicrosoftSQL Server target, Informatica invokes the bulk API with default settings, bypassing databaselogging.If you select Bulk for other database types, thePowerCenter Server reverts to a normal load.Loading in bulk mode can improve sessionperformance, but limits your ability to recoverbecause no database logging occurs.Note: Choose Normal mode if the mappingcontains an Update Strategy transformation.Tip: When you choose Bulk mode for Microsoft
SQL Server or Oracle targets, define a largecommit interval.Consider the following database limitations whenyou choose Bulk mode when loading to Oracle:
Do not define CHECK constraints in the
database. Do not define primary-foreign keys in the
database. However, you can define primary-foreign keys for the target definitions in theDesigner.
Do not create indexes in the database. When you use the LONG datatype, verify it
is the last column in the table.
