I'm trying to import a csv in Teradata but I just get the message "query invalid" with no explanation. I tried changing the slashes to forward without any difference
create volatile table temp (
a varchar(255)
);
.IMPORT vartext ',' FILE = 'F:\xyz\abcdef.csv', skip = 1;
delete from temp;
.QUIET ON
.REPEAT *
USING (
a varchar(255)
)
INSERT INTO temp(a)
VALUES (
:a
);
.QUIT
.LOGOFF

I am using ESP8266 and want to use a SQLite db stored in an SD.
Here is how I created the tables in SQL Online IDE:
CREATE TABLE "nfc_tag" (
"id" TEXT NOT NULL UNIQUE,
"value" TEXT NOT NULL,
PRIMARY KEY(id)
);
CREATE TABLE "tag_log" (
"tag_id" TEXT NOT NULL,
"datetime" TEXT NOT NULL,
);
And when I run:
int query_tag(const char *tag) {
const char *null;
// Prepare the statement
sqlite3_stmt *statement;
if (sqlite3_prepare_v2(db, "SELECT value FROM nfc_tag WHERE id = ?;", -1, &statement, &null) != SQLITE_OK) {
Serial.print("Unable to prepare: ");
Serial.println(sqlite3_errmsg(db));
return 0;
}
}
Everything is ok.
But I want tag_id to be a foreign key to id in nfc_tag, so I recreated the db and created the tables with this statement:
CREATE TABLE "nfc_tag" (
"id" TEXT NOT NULL UNIQUE,
"value" TEXT NOT NULL,
PRIMARY KEY(id)
);
PRAGMA foreign_keys = ON;
CREATE TABLE "tag_log" (
"tag_id" TEXT NOT NULL,
"datetime" TEXT NOT NULL,
FOREIGN KEY("tag_id") REFERENCES "nfc_tag"("id")
);
And now, when I run the same code, I get Unable to prepare: file is encrypted or is not a database
I have not encrypted the db, and I can open it in VSCode and DB Browser for SQLite, so I guess it is not encrypted. I don't know if it is because of the foreign key, but it shouldn't be a problem because of the PRAGMA statement.
Any help would be appreciated, thanks in advance!
I have a simple tpt script (given below) to load image into CLOB column in an empty table.

To load data into table I'm using two text files:
File have all the Varchar column values and Clob data location.
Example data in file: <Clob_File_Location>,Name,123
Clob column value
Example data in file: Image.png
After executing the above tpt, I get message as "data loaded successfully". But when I check the table in place of image in Clob column text is loaded.
Can someone help in letting me know what I might be doing wrong.
What I want to do is check in my database if my table exists, if yes drop it. Here is my .tpt :

Do you have any idea ? I have tried multiple things, such as :
SELECT 1 FROM dbc.TablesV WHERE databasename = #Db AND TABLENAME ='TEST_DEL';
CASE WHEN ACTIVITYCOUNT = 1
THEN (DROP TABLE #Table)
ELSE ( QUIT )
END;
All my variables have been declared. I feel that it is a problem with using single quotes inside que statement but I am not sure and I don't know how to resolve it. Thank you very much for your time.
The solution that Fred recommended me to try in the comments worked just fine :
I think this is due to use of NULL but SELECT is not valid for DDL operator. The recommended way to do this is simply pass a DROP to the operator and tell it to ignore "not found" (and consider that success), i.e. ErrorList='3807'

Call TPT:

Above TPT script is failing with following error:

Am i missing any detail in here?
The messages certainly could be clearer, but the issue is that NAME is a restricted word.
I'm trying to create some deployment tools and I don't want to use BTEQ. I've been trying to work with the Teradata.Client.Provider in PowerShell but I'm getting syntax errors on the creation of a table.
[Teradata Database] [3706] Syntax error: expected something between
';' and the 'IF' keyword.
SELECT * FROM DBC.TablesV WHERE DatabaseName = DATABASE AND TableName = 'MyTable';

)
PRIMARY INDEX PI_MyTable_MyColLogId(MyColLogId);
LABEL EndStep1;
I would rather not use BTEQ as I've not found it has worked well in other deployment tools we have created and requires a bit of hacks. Is there anything I can use that would avoid using that tool?
What Parse error?
The CREATE will fail due to double INTEGER in MyColId and VARCHAR(max) in ExceptionOutput, it's an unknown datatype in Teradata.
