+Dataset used for training text to sql.
+I've pre-tokenized this for faster loading. 
+
+
+Here is the tokenizer code:
+```
+def tokenize_function(example):
+    start_prompt = "Tables:\n"
+    middle_prompt = "\n\nQuestion:\n"
+    end_prompt = "\n\nAnswer:\n"
+
+    data_zip = zip(example['context'], example['question'])
+    prompt = [start_prompt + context + middle_prompt + question + end_prompt for context, question in data_zip]
+    example['input_ids'] = tokenizer(prompt, padding="max_length", truncation=True, return_tensors="pt").input_ids
+    example['labels'] = tokenizer(example['answer'], padding="max_length", truncation=True, return_tensors="pt").input_ids
+#     print(prompt[0])
+#     print()
+
+    return example
+```
