Are you sure Windows Explorer isn't just hiding the extension? AlexPoole - I saw after my post that sqlldr should be creating with a default. I'm using a DOS window for all of this. Add a comment.

David Aldridge David Aldridge Yes; if it can't create a log file it terminates immediately. I'm inclined to agree - though I think it is a bit rubbish that I can't set the logfile within the control file if it can't read the control file etc I would have expected it to log to the screen. Open your Web project and load the file that contains the ListBox.
Query the table's information. In my experience troubleshooting SQL , install issues are one of the hardest and most time-consuming processes. Most of the time it's a hit-and-miss.

If you omit end, the length of the continuation field is the length of the byte string or character string. If you use end, and the length of the resulting continuation field is not the same as that of the byte string or the character string, the shorter one is padded.
Character strings are padded with blanks, hexadecimal strings with zeros. A string of characters to be compared to the continuation field defined by start and end, according to the operator.
The string must be enclosed in double or single quotation marks. The comparison is made character by character, blank padding on the right if necessary. A string of bytes in hexadecimal format used in the same way as str. X'1FB would represent the three bytes with values 1F, B0, and 33 hexadecimal. The default is to exclude them. This is the only time you refer to positions in physical records. All other references are to logical records.
That is, data values are allowed to span the records with no extra characters continuation characters in the middle. Assume that you have physical records 14 bytes long and that a period represents a space:. Assume that you have the same physical records as in Example Note that columns 1 and 2 are not removed from the physical records when the logical records are assembled. Therefore, the logical records are assembled as follows the same results as for Example It defines the relationship between records in the datafile and tables in the database.
The specification of fields and datatypes is described in later sections. The table must already exist. If the table is not in the user's schema, then the user must either use a synonym to reference the table or include the schema name as part of the table name for example, scott.
That method overrides the global table-loading method. The following sections discuss using these options to load data into empty and nonempty tables. It requires the table to be empty before loading. After the rows are successfully deleted, a commit is issued. You cannot recover the data that was in the table before the load, unless it was saved with Export or a comparable utility. If data does not already exist, the new rows are simply loaded.
The row deletes cause any delete triggers defined on the table to fire. For more information on cascaded deletes, see the information about data integrity in Oracle9i Database Concepts. To update existing rows, use the following procedure:. It is only valid for a parallel load.
Parameters for Parallel Direct Path Loads. You can choose to load or discard a logical record by using the WHEN clause to test a condition in the record. The WHEN clause appears after the table name and is followed by one or more field conditions.
For example, the following clause indicates that any record with the value "q" in the fifth column position should be loaded:. Parentheses are optional, but should be used for clarity with multiple comparisons joined by AND, for example:. If all data fields are terminated similarly in the datafile, you can use the FIELDS clause to indicate the default delimiters. Terminator strings can contain one or more characters.
You can override the delimiter for any given column by specifying it after the column name. Assume that the preceding data is read with the following control file and the record ends after dname:. In this case, the remaining loc field is set to null. This option inserts each index entry directly into the index, one record at a time.
Instead, index entries are put into a separate, temporary storage area and merged with the original index at the end of the load.
This method achieves better performance and produces an optimal index, but it requires extra storage space. During the merge, the original index, the new index, and the space for new entries all simultaneously occupy storage space. The resulting index may not be as optimal as a freshly sorted one, but it takes less space to produce. It also takes more time because additional UNDO information is generated for each index insert.
This option is suggested for use when either of the following situations exists:. The remainder of this section details important ways to make use of that behavior.
Some data storage and transfer media have fixed-length physical records. When the data records are short, more than one can be stored in a single, physical record to use the storage space efficiently. For example, assume the data is as follows:. The same record could be loaded with a different specification.
The following control file uses relative positioning instead of fixed positioning. Instead, scanning continues where it left off. A single datafile might contain records in a variety of formats.
Consider the following data, in which emp and dept records are intermixed:. A record ID field distinguishes between the two formats. Department records have a 1 in the first column, while employee records have a 2. The following control file uses exact positioning to load this data:.
The records in the previous example could also be loaded as delimited data. The following control file could be used:. It causes field scanning to start over at column 1 when checking for data that matches the second format. A single datafile may contain records made up of row objects inherited from the same base row object type. For example, consider the following simple object type and object table definitions in which a nonfinal base object type is defined along with two object subtypes that inherit from the base type:.
The following input datafile contains a mixture of these row objects subtypes. A type ID field distinguishes between the three subtypes.

It does not apply to the direct path load method because a direct path load uses the direct path API, rather than Oracle's SQL interface. Oracle Call Interface Programmer's Guide for more information about the concepts of direct path loading. The bind array must be large enough to contain a single row. Otherwise, the bind array contains as many rows as can fit within it, up to the limit set by the value of the ROWS parameter.
Although the entire bind array need not be in contiguous memory, the buffer for each field in the bind array must occupy contiguous memory. Large bind arrays minimize the number of calls to the Oracle database server and maximize performance. In general, you gain large improvements in performance with each increase in the bind array size up to rows. Increasing the bind array size to be greater than rows generally delivers more modest improvements in performance.
The size in bytes of rows is typically a good value to use. It is not usually necessary to perform the detailed calculations described in this section. Read this section when you need maximum performance or an explanation of memory usage.
