Generate Embeddings: SQL and PL/SQL Examples

In these examples, you can see how to generate one or more vector embeddings from text strings and PDF documents.

• Convert Text String to Embedding
  You can vectorize text strings like this for chatbots or information-retrieval applications, where you want to directly convert a user's input text to a query vector and then run it against vector index for a fast similarity search.
• Convert File to Text to Chunks to Embeddings
  You can run parallel or step-by-step transformations like this for standalone applications where you want to review, inspect, and accordingly amend results at each stage and then proceed further.
• Convert File to Embeddings
  You can directly extract vector embeddings from a PDF document, using a single-step statement.
• Generate and Use Embeddings for End-to-End Search
  In this example, you first generate embeddings from textual content by using an ONNX model, and then populate and query a vector index. At query time, you also vectorize the query criteria on the fly.
