Top Forums Shell Programming and Scripting Shell script for converting file contents into CSV Post 302284623 by rish_max on Friday 6th of February 2009 01:30:08 AM

Thanx for quick reply, but it doesn't work for me.
I rephrase my problem:
Every row in a file should have 5 seperate columns in which values are tab seperated.
and there are some blank values, say column 4 of row 2 is blank and column 3 of row 3 is blank. I need to first fill this blank value with 'null' and then convert it into CSV
i.e the script should consider the tab value as blank and replace it with ',' but should not consider the blank value of a column as blank space.
sed will replace tabs and blank values of a column with ',' so the output becomes
row 1 has all 5 values seperated with comma
row 2 has first 3 values seperated with comma and then sed consider the tab space and blank value as blankspace and replace it with comma and then write the 5th column value so the output becomes val1,val2,val3,val5. It should be like val1,val2,val3,null,val5

ifx_query - Send Informix query

SYNOPSIS
resource ifx_query (string $query, resource $link_identifier, [int $cursor_type], [mixed $blobidarray]) DESCRIPTION
Sends a $query to the currently active database on the server that's associated with the specified link identifier. For "select-type" queries a cursor is declared and opened. Non-select queries are "execute immediate". For either query type the number of (estimated or real) affected rows is saved for retrieval by ifx_affected_rows(3). If the contents of the TEXT (or BYTE) column allow it, you can also use ifx_textasvarchar(1) and ifx_byteasvarchar(1). This allows you to treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with blob id's. With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer value). You can get the value of the blob as a string or file with the blob functions (see below). PARAMETERS
o $query - The query string. o $link_identifier - The link identifier. o $cursor_def - This optional parameter allows you to make this a scroll and/or hold cursor. It's a bitmask and can be either IFX_SCROLL, IFX_HOLD, or both or'ed together. I you omit this parameter the cursor is a normal sequential cursor. o $blobidarray - If you have BLOB (BYTE or TEXT) columns in the query, you can add a $blobidarray parameter containing the corresponding "blob ids", and you should replace those columns with a "?" in the query text. RETURN VALUES
Returns valid Informix result identifier on success, or FALSE on errors. EXAMPLES
Example #1 Show all rows of the "orders" table as a HTML table <?php ifx_textasvarchar(1); // use "text mode" for blobs $res_id = ifx_query("select * from orders", $conn_id); if (! $res_id) { printf("Can't select orders : %s <br />%s<br /> ", ifx_error(), ifx_errormsg()); die; } ifx_htmltbl_result($res_id, "border="1""); ifx_free_result($res_id); ?> Example #2 Insert some values into the "catalog" table <?php // create blob id's for a byte and text column $textid = ifx_create_blob(0, 0, "Text column in memory"); $byteid = ifx_create_blob(1, 0, "Byte column in memory"); // store blob id's in a blobid array $blobidarray[] = $textid; $blobidarray[] = $byteid; // launch query $query = "insert into catalog (stock_num, manu_code, " . "cat_descr,cat_picture) values(1,'HRO',?,?)"; $res_id = ifx_query($query, $conn_id, $blobidarray); if (! $res_id) { /* ... error ... */ } // free result id ifx_free_result($res_id); ?> SEE ALSO
