HXTT Text(CSV)
Float and Date in ODBC schema files

Hello,

I am trying you csv jdbc driver and setup the connection like so:

jdbc:text://///server/classic/DMS Files/undated extracts?odbcSchemaFile=schema.ini.hxt (using UNC path and shared folder)

the schema file contains this :

[bildtl.csv]
ColNameHeader=False
Format=Delimited(|)
MaxScanRows=25
CharacterSet=OEM
Col1=F1 Char Width 255
Col2=F2 Integer
Col3=F3 Char Width 255
Col4=F4 Integer
Col5=F5 Char Width 255
Col6=F6 Date
Col7=F7 Char Width 255
Col8=F8 Float
Col9=F9 Integer
Col10=F10 Float
Col11=F11 Char Width 255
Col12=F12 Float
Col13=F13 Char Width 255
Col14=F14 Char Width 255
Col15=F15 Integer
Col16=F16 Date

It does not like FLOAT so I have changed to be DOUBLE (this is ok)

It is OK with Date but you column always comes back empty when it should come back with 12/12/2007 or 12/12/2007 00:00:00.0 or 2007-12-12 or even 2007-12-12 00:00:00.0

the csv file contains 12/12/2007

Who produce that shcmai.ini for bildtl.csv? What's your ODBC driver?
It will be translated into
create table "bildtl.csv" (F1 char( 255),F2 INTEGER,F3 char( 255),F4 INTEGER,F5 char( 255),F6 TIMESTAMP('yyyy-MM-dd hh:mm:ss'),F7 char( 255),F8 FLOAT,F9 INTEGER,F10 FLOAT,F11 char( 255),F12 FLOAT,F13 char( 255),F14 char( 255),F15 INTEGER,F16 TIMESTAMP('yyyy-MM-dd hh:mm:ss'),_CSV_Separator char(1) default '|',_CSV_Header boolean default false).

The schema was generated by Microsoft ODBC txt/csv driver version 4.00.6307.00

the only real issue i have with the driver is that is does not return a pure Date field if it is not correctly formatted e.g. 12/12/2007 should return as 12-12-2007 00:00:00.0 or 2007-12-12 00:00:00.0 instead it returns the date empty.

thanks

v3.1.079 can parse all kinds of date, time, timestamps format, without prefined date format, or default date format. Your schema.ini will be parsed as:
create table "bildtl.csv" (F1 char( 255),F2 INTEGER,F3 char( 255),F4 INTEGER,F5 char( 255),F6 DATE,F7 char( 255),F8 DOUBLE,F9 INTEGER,F10 DOUBLE,F11 char( 255),F12 DOUBLE,F13 char( 255),F14 char( 255),F15 INTEGER,F16 DATE,_CSV_Separator char(1) default '|',_CSV_Header boolean default false)

The latest package will be available in 24 hours. Thanks for your requirement.

sample of schema.ini for the csv file
[baltrn.csv]

Col11=F11 Char Width 255
Col12=F12 Char Width 255
Col13=F13 Char Width 255
Col14=F14 Date

actual results returned was none, tried on a different file and dates still don't work as expected.

It said:
java.sql.SQLException: Failed to get a double value from java.lang.String: PATIENT

After changed
Col5=F5 Integer
into
Col5=F5 Char Width 255

It can return values:)

You can know your issue if you used the following code:

catch( SQLException sqle )
{
do
{
System.out.println(sqle.getMessage());
System.out.println("Error Code:"+sqle.getErrorCode());
System.out.println("SQL State:"+sqle.getSQLState());
//sqle.printStackTrace();
}while((sqle=sqle.getNextException())!=null);
}

If you use ignoreDirtyData connection property, you can still use Col5=F5 Integer .

>dates still don't work as expected.
Please download the latest package.

BTW, odbcSchemaFile is only using for old ODBC compatibility. If you hasn't odbc schema file information, you need to prepare it in advance, and let HXTT Text (CSV) to do auto data detection.

>the above example shows that dates come back empty
In my test, it will show 2007-10-09 .

>it doesn't detect the | as a seperator
You shoud use _CSV_Separator=| connection property. For instance, "jdbc:csv:/f:/textfiles?_CSV_Separator=|;_CSV_Header=true;

Checked. You should be using http://www.hxtt.com/text.zip, please login through http://www.hxtt.com/download.jsp?product=text, then you can download the latest package, for instance Text_JDBC30.jar.
